Description
BACKGROUND

The present invention relates generally to the field of computerized supply chain management, and more specifically to maintaining actor accountability within a distributed supply chain.


Sealed or packaged perishable products (e.g., raw food, certain types of medications, etc.) are often shipped with an indication of an expected product lifespan (e.g., a “Best Before” date, etc.), so that vendors and consumers can know whether it is safe to consume the product. Unfortunately, due to various conditions (e.g., overall weather encountered, exposure to humidity, nature of the product, and handling methods) present as the product travels through a supply chain to a consumer, it can be difficult for an end consumer to know whether the product is really consumable until the “Best Before” date.


Perishable products may be handled by several parties (especially in decentralized supply chain networks, where the product moves between distant actors and may experience several product handling environments) when moving from production to purchase, and “Best Before” dates can be inaccurate. For example if a product is exposed to harsh environmental conditions or has been poorly handled, it may not be safe to consume the product even within the “Best Before” date range. In those cases, the product should by discarded early to avoid endangering consumers. It can be very difficult to know how a product has been handled on the way to a consumer and whether an indicated “Best Before” date is accurate.

Now with combined reference to the Figures generally and with particular reference to FIG. 1 and FIG. 2, an overview of a method of maintaining accountability for product lifespan changes in a decentralized supply chain network usable within a system 100 as carried out by a server computer 102 having optionally shared storage 104 will be provided; a more detailed discussion will follow, as a method according to embodiments of the invention is described.


The server computer 102 is in operative communication with a source of product metadata 106. According to aspects of the invention, the metadata includes product identification indicia 402 and an initial calculated lifespan value 404 (as seen e.g., in table 400 of FIG. 4). The server computer 102 is in operative communication with an Internet of Things (IoT) interface 108, allowing IoT communication regarding tracked product interactions. The server computer 102 is in operative communication with supply chain product interaction metadata 110. According to aspects of the invention, this includes IoT sensor input 504, 506, 508 (see, e.g., table 500 in FIG. 5) and an indication of responsible actors 406, 412, 418 (e.g., product processors, product handlers, etc.) associated with for each supply chain transaction phase 502 (e.g., “Production”, “Shipping,”, and “Purchase” as seen e.g., in table 500 of FIG. 5). The server computer 102 includes a Product Lifespan Assessment Module “PLAM” 112. According to aspects of the invention, the PLAM 112 includes product treatment rules that describe expected handling metrics for various products, along with regression models used by the server computer 102 to determines product lifespan values. The server computer includes Reputation Assessment Module “RAM” 114 that, according to aspects of the invention processes actor reputation values and assigns penalties for actors with a performance rating below a penalty threshold. The server computer 102 is in operative communication with distributed database 116. According to aspects of the invention, the distributed database 116 immutably holds, among other things, product lifespans, product interaction data, and actor performance ratings. The server computer 102, via the distributed database 116 (e.g., a distributed ledger, a blockchain network, etc.) is operative communication with one or more networked computers 118. According to aspects of the invention, each networked computer 118 includes a private transactional database to capture processing data for transactions with respective peers.


Now with specific reference to FIG. 2, and to other figures generally, aspects of a method of maintaining accountability for product lifespan changes in a decentralized supply chain network will be described. The server computer 102 at block 202 identifies a network including a distributed database 116 operationally connected to a plurality of computers 118 and a source of metadata 106 associated with a product being tracked. According to aspects of the invention, a blockchain network is setup to track product “best before” date values 404, 408, 414 and handling (e.g., as seen in table 500) of perishable products as they move through the transaction phases within the supply chain.


According to aspects of the invention, each member (e.g., actor associated with phase transactions) in the supply chain involved with handling of the product is included as a participant in the network. According to aspects of the invention, an end to end, containerized system is incorporated with build the distributed network (e.g., on top of a blockchain). According to aspects of the invention, each participant must be authenticated and authorized by a network level certificate authority to gain access. The containerized system includes a front end 108 with built-in access to an internet of things (IoT) platform, a Machine Learning (ML) model (e.g., one or more product-specific regression models to predict shelf life for the modeled product type, sensor handling metadata 110, a rule engine 112 where product-specific handling rules will be stored, a distributed database system 116 that stores sensor-based product interaction metadata 110 (including e.g., handling activity location-based weather data). As noted above, each participant 118 maintains a private transactional database systems to capture processing data for transactions with respective peers.


The server computer 102, via Product Lifespan Assessment Module “PLAM” at block 204 generates data models describing a tracked products. According to aspects of the invention, the server computer models a perishable product via a blockchain smart contract as an array of key/value pair attributes that are used to store aspects of captured sensor data (as shown, e.g., in FIG. 5 such as temperature 504, humidity 506, CO2 levels 508, etc.) at a specific location and noted point in time (e.g., a transaction phase). According to aspects of the invention, keys in this model are a composite of sensor and product container identifiers (e.g., available as part of product metadata 106). Aspects of the invention record sensor readings 504, 506, 508 (available as part of supply chain product interaction metadata 110) associated with phases (502) of product interaction, associated with product progress though the supply chain. The machine learning model 112 leverages these readings as features when computing product transaction phase-related lifespan values 408, 414 (e.g., 2nd and 3rd phase “best before” dates). According to aspects of the invention, the ML model applies an algorithm trained with a training data set associated with various products to be tracked.


According to aspects of the invention, products are located in matching product containers (not shown), and the containers include product identifying indicia (available as part of product metadata 106), and the server computer 102 uses this indicia when identifying a tracked product. The server computer also uses the indicia select a corresponding machine learning model and uses the corresponding model to determine a dynamic (e.g., updated during supply chain interaction) lifespan (e.g., “best before” date) for the identified product. According to aspects of the invention, the lifespan calculation is based, at least in part on collected sensor data shown in table 500. According to aspects of the invention, tracked product travel through the supply chain occurs in several distinct phases, and each phase has one or more key actors (e.g., product handlers, etc.) that interact with the product in that phase. In an embodiment, the phases include “ship”, “receive”, and “buy.” As shown FIG. 5, the phases may also include “production.”


According to aspects of the invention, the server computer 102, calculates via PLAM 112 at block 204, using a Machine Learning (ML) model trained to process quality impacting values 110, initial and second product lifespan values 404, 406, based at least in part, on an initial set T1, H1, C1 and a second set of quality impacting values T2, H2, C2 (both sets of impacting values are represented schematically in table 500).


According to aspects of the invention, the server computer 102 at block 206, in response to determining the initial and second product lifespan values, records those values in the distributed database 116. In an embodiment, a first supply chain participant 406 (e.g., a product producer) manufactures and ships an item and, as part of a “shipping” smart contract automated transaction, an initial lifespan indicating value (e.g. a “best before” date, useable life range, etc.) is calculated and propagated to the blockchain network database 116, as a first block immediately following a network-originating genesis block.


The server computer 102 determines via reputation assessment module “RAM” 114 at block 208, a performance rating attributed to a second phase actor 412 based, at least in part, on a calculated change 410 between the initial and second product lifespan calculations 404, 408. In an embodiment, the second phase participant 412 (e.g., product handler or other actor) in the network receives a container associated with the tracked product. As part of an automated “receive” smart contract transaction, a second phase best before date 408 is computed to determine whether the second lifespan 408 (e.g., product consumption window) is same as the initially-calculated lifespan 404.


According to aspects of the invention, each member of the supply chain is contractually obligated to periodically captures product handing data via sensors and forward this data 110 via an IoT Gateway 108 to be committed to blockchain through automated, smart contract transactions, and fines are levied, if a participant does not capture and commit product handling data 110 to the distributed network (e.g., blockchain) 116.


According to aspects of the invention, blockchain client APIs are used to extract the data 110 from a network 116 at each point to train the ML prediction model. Perishable item-based predictive machine learning models use this data to compute the shelf life of each product at each point of transaction in the network. Data at predetermined, phase-relevant transaction points, as well as all historical data, is taken into consideration when creating these models. Regression models are the preferred predictive models and are available for each transaction entry to dynamically predict a current product lifespan based on handling data 110 for the given product. In an embodiment, a network event monitor (not shown) notes when product sensor data 110 is committed to the blockchain 116, and the addition of data triggers an API call. According to aspects of the invention, the call reads, via PLAM 112, the available sensor collected data 110 and the PLAM 112 uses the ML model (e.g., linear regression algorithm or other method selected by one skilled in this filed) to compute product lifespan 404, 408, 414 during ship, receive and buy transactions.


It is noted that the decentralized supply chain may include many phases and additional phase actors. In an embodiment, the supply chain may include a third 418 (or more) phase-relevant actors, and a third (or further) lifespan change 416 may be present and calculated. Any reduction or lifespan reduction 410, 416 due to potential mishandling by the phase-relevant actors 406, 412, 418 will results in an update to the responsibility value 604 (as represented schematically in FIG. 6) associated with that actor and phase 502. In an embodiment, actor reputation values 604 are calculated and stored as part of the distributed network content state for the responsible actor participant as a key/value store with the key being the participant's identifier 602 and value being the updated responsibility rating 604.


The product lifespan values are product specific, and the server computer 102 via PLAM 112 stores and applies specific rules for each type of product. For example, if vendor is importing beans from a distant location, it is noted that handling data and location based weather data might be vary throughout product travels through the supply chain, and a Rule for beans will consider those factors. In an embodiment, an initial product lifespan for beans is 100. According to aspects of the invention, actor rating=(any previous phase lifespan)−(current phase lifespan)*(Rule determined phase weighting index, which ranges between 0.001 and 0.025)=previous lifespan−current responsibility rating*(0.001 to 0.025). According to aspects of the invention, when an actor participant 602 reduces 410, 416 a product lifespan, the server computer 102, via RAM 114, reduces the actor performance rating 604. The product will be eligible for consumption when the relevant phase actor 602 performance rating is >=95.


If a product is not consumable, the server computer 102 will reduce, via RAM 114, the performance rating of the actor 602 contributing most to the lifespan reduction (e.g., as indicated by lifespan changes 410, 416 or by unacceptable product handling metadata 110).


With reference to FIG. 3, the server computer 102 via Reputation Assessment Module “RAM” 114 processes actor reputation ratings and assigns penalties. According to aspects of the invention, the server computer via RAM 114 at block 302, determines, whether an actor performance rating is below penalty threshold. According to aspects of the invention, when the last block is written to the network, responsibility rating represents the penalty enforced on a participant or multiple participants in the network and accessible by all stakeholders. Repeat offenders stand to lose business for negligence in product handling. This combined with dynamic computation of best before date at every transaction phase in the network ensures the consumption viability of perishables is best preserved and accessible to all supply chain network participants. According to aspects of the invention, the performance rating 604 is a unitless quantity that indicates the cumulative product treatment trends associated with an actor generally. In an embodiment, the performance rating 604 can vary from 0 to 100, with 100 representing the best rating. If the performance rating for an actor falls below a penalty threshold of 95, the RAM 114 assigns, in block 304, a penalty to the actor in and updates the distributed database 116 accordingly. In an embodiment, the penalty may be a monetary fine, a reduction in business preference, or another tactic selected by one skilled in this field. After relevant penalties are assigned, flow returns to block 210, where the server computer 102 records the second phase actor performance rating to the network 116.


According to aspects of the invention, a transaction entered on the distributed network causes update to the previously-computed lifespan. Before any transaction block is processed and consensus reached to commit the block, smart contract/chain code is executed to compute a current lifespan (e.g., “best before” date) of the product. The updated lifespan is written to the network world state. According to aspects of the invention, incorporate smart contract business logic prevents inauthentic transactions from being propagated (e.g., committed to the network).

It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.


Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.


Characteristics are as follows:


On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.


Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).


Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).


Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.


Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.


Service Models are as follows:


Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.


Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.


Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).


Deployment Models are as follows:


Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.


Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.


Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.


Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).


A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.


Referring now to FIG. 8, illustrative cloud computing environment 2050 is depicted. As shown, cloud computing environment 2050 includes one or more cloud computing nodes 2010 with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone 2054A, desktop computer 2054B, laptop computer 2054C, and/or automobile computer system 2054N may communicate. Nodes 2010 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment 2050 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 2054A-N shown in FIG. 8 are intended to be illustrative only and that computing nodes 2010 and cloud computing environment 2050 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).
