Towards an Agile and Collaborative Platform for Managing Supply Chain Uncertainties
Nowadays, one of the main challenges for Supply Chains is the management of disruptions and uncertainties. Turbulence and instability have now to be considered as the ‘normal’ situation. Future Supply Chains should be able to cope with this new context to stay competitive. To solve this issue, new approaches and technologies have to be designed in order to improve the agility capability of supply networks. To contribute to this new problem statement, as a part of the H2020 C2NET research project, this paper proposes a concrete research framework. The research aim consists in defining precise research orientations in one hand, and structuring a set of technical tasks able to result in an agile and collaborative platform on the other hand. Basically, the main components of the research framework are presented and the expected impacts are discussed.
KeywordsSupply Chain Uncertainty Collaborative platform Agility Research framework
Modern Supply Chains are continuously challenged by unexpected disruptive events that are increasing in their frequency and effects: supply failures, demand changes, internal disruptions, etc. In this context, turbulence and instability can be no longer considered as an episodic crisis, rather the “norm” or the default status. The question is then to know how the Supply Chains can strive and gain in such disruptive environments and which supportive roles can the technology play. Current IT and decision-making systems are designed to run in more or less “stable” environment. Disturbances are captured by exception handling mechanisms. Thus, calling for a new perspective in Supply Chains design and engineering. While current Supply Chains are tempting to be robust, tomorrow’s Supply Chains need to become agile.
The C2NET Data Collection Framework (DCF) that collects in real-time information from processes and products within the supply chain;
The C2NET Optimizer (OPT) that allows providing production plans and decisions to all concerned supply chain partners;
The C2NET Collaboration Tools (COT) that proposes a set of services able to facilitate the achievement of agreements and drastically reduce response time and cost of decision-making processes.
In this paper we focus only on the collaboration tools (C2NET-COT). The problem statement of this set of tools is to develop a new approach for facilitating collaborative demand, production and delivery plans along the supply network. Basically, the technical ambition is to design a modular architecture for interoperability of intra plant and extra plant processes in conjunction with mobile, collaborative tools for data sharing, data analytics and knowledge-based systems, at factory and at supply network level.
The paper is split up into three main sections. First a literature selection will propose to underline the concepts of “Agile Supply Chains” and “Collaborative networks”. On this basis, we will propose in a second part a research framework able to structure the future developments on this subject. Then, a third part will discuss the main impacts that should be obtained at the end of this research project.
2 Literature Selection
Many companies have not fully recognized the nature of systemic supply chain risk and have continued to focus on seeking efficiency improvements (Christopher and Peck 2004). These authors argue that a new priority consist in searching for supply chain strategies that embody a significantly higher degree of resilience. Resilience implies flexibility and agility. Its implications extend beyond process redesign to fundamental decisions on sourcing and the establishment of more collaborative supply chain relationships based on far greater transparency of information (Christopher and Peck 2004).
2.1 Agile Supply Chains
Effectiveness: ability to satisfy the customer demand;
Completeness: ability to satisfy totally the customer demand;
Reliability: ability to respect the customer delivery lead time;
Responsiveness: ability to respond quickly which requires to: (i) detect quickly changes [Visibility], (ii) decide quickly on the adaptation to make using flexibility [Reactivity], and (iii) implement quickly the decisions [Velocity].
Another definition has been proposed by (Benaben 2012):
Agility = (Detection + Adaptation) × (Effectiveness + Responsiveness)
Delayed choice: the process is partially defined during the design time and finalized at the execution. In this approach, the implementation of some sub-processes is chosen within a predefined list at the moment of the process execution. This approach is implemented in the YAWL system (Adams et al. 2005).
Delayed design: the process is partially defined, but some sub-processes are not identified during the design. This approach suggests to come back to a specific design time when required during the execution.
Risks management: various alternative paths are identified during the design time in order to adapt to risks, threats or opportunities. One path is finally chosen during each execution of the process. With this approach the number of paths to be identified can be too important in practice.
AdHoc design: this approach extends the concept of delayed design. The sequence of activities can be changed, some tasks can be added or cancelled or repeated. It is the more common approach (Adams et al. 2005).
The C2NET Collaborative Platform will propose a concrete support able to manage the agility of the collaborative situation, especially in manufacturing network environment. The main contribution of the C2NET Project regarding extent literature on this point consists in making agile Supply Chains concrete. Specific objectives will include the design and the implementation of an integrated system able to supervise, detect, adapt and assess the collaborative situation.
2.2 Collaborative Networks
The way how manufacturing and service industries manage their businesses is changing due to the emerging new competitive environments. According to (Camarinha-Matos and Afsarmanesh 2005) the enterprises’ success in the new dynamic environments is associated to the improved competencies in terms of new business models, strategies, governance principles, processes and technological capabilities of manufacturing enterprises of 2020. Moreover, especially for SMEs, the participation in collaborative networks is also a key issue for any enterprise that is willing to achieve differentiated and competitive strengths. Consequently, establishing collaborative relationships becomes an important issue to deal with customer needs, through sharing competencies and resources. Collaborative Networks consist of a variety of heterogeneous autonomous entities, geographically distributed, in which participants collaborate to achieve a common goal and base their interactions through computer networks. SMEs are characterized by limited capabilities and resources; therefore, in order to overcome possible barriers that can appear when establishing collaboration, joint efforts must be performed to achieve the desired collaborative scenarios. When establishing collaboration, networked partners share information, resources and responsibilities to jointly plan, implement, and evaluate a program of activities to reach a common goal and therefore jointly generate value. Thus, establish collaborative relationships imply sharing risks, resources, responsibilities, losses, rewards and trust. Collaborative networks manifest in a large variety of forms, such as virtual organizations, virtual enterprises, dynamic supply chains, professional virtual communities, collaborative virtual laboratories (Camarinha-Matos and Afsarmanesh 2005) and collaborative non-hierarchical networks (Poler et al. 2013). The main challenges for creating collaborative networks are presented in VOmap and are divided into five focus areas (i) socio economic, (ii) VO management, (iii) ITC support services, (iv) ICT Infrastructures and (v) formal models and theories.
Based on this background, the C2NET project will focus on the research and technical development to overcome possible barriers encountered when enterprises participate in collaborative networks characterized by distributed partners with decentralized information. The C2NET project will allow exploiting enterprises’ capabilities and resources to efficiently succeed on the participation in collaborative networks. Specific objectives will include the design of cloud computing ICT, due to the advantages encountered for manufacturing and service industry networks, and the development of an integrated framework, consisting of models, methodologies and tools, to support enterprises in dealing with decentralized decision making within collaborative networks.
3 Research Framework
Supervision: Define and implement the exploitation mechanisms to use collected data (from IoT, from monitoring or any other means) in order to maintain models of the collaborative situation.
Detection: Define and implement the exploitation mechanisms of the situation models in order to diagnose any source of divergence of the collaboration with regard to the expected situation.
Adaptation: Define and implement the reaction mechanisms to deduce from the analysis of the situation models, the appropriate adjustments to propose to the running collaborative situation.
Assessment: Define, deploy, measure and exploit Key Performance Indicators (KPI) to ensure the relevant evaluation of the consequences of the adaptation actions
Hereafter, we give some requirements regarding tasks that have to be done to develop the previously discussed elements.
3.1 The Knowledge Base
Based on both a state-of-the-art on collaborative knowledge bases (domain ontologies vs. collaborative situation ontologies) and the reference models, this first design aims at defining and implementing an exploitable knowledge base about collaborative situations. This knowledge base should be compliant with any collaborative situation concerned by the C2NET project in terms of concerned business domain and concerned collaborative structure. The obtain knowledge base should be open and usable by the four agility services.
3.2 The Modeling Service
This second design aims at defining and implementing the first agility service. This task should define the translation mechanisms that could allow to update the knowledge base according to the continuously gathered data. This task includes a strong work on data format interpretation (syntactic view) and also on data content interpretation (semantic view).
3.3 The Detection Service
This third design aims at defining and implementing the second agility service. This service is responsible for the detection of irregular situations based on the captured data. Actually, once the knowledge base implemented is populated with relevant data gathered thanks to the data acquisition framework, the detection mechanism can be triggered. Furthermore, the detection mechanism can take benefit from semantically described assets and processes in order to reveal something is going wrong with the occurring process.
Considering an enacted business process, the ability of surveying the different participants collaborating to achieve it becomes complex as these are probably belonging to different entities and abide by different rules. The adoption of the ESB technology as an interoperable framework for data collection augments the ability of applying a monitoring and detection mechanisms that will ensure such a functionality. More precisely, we will implement an event-based architecture that will subscribe to the exchanges data and that will trigger events expressing the nature of the exchange (time, sender, receiver, etc.). Once compared with the required pattern we will be able to detect if the data is relevant with regard to the required one. When the detection mechanism is not triggered by a produced event, it parses the gathered data recent and historical that is stored in the knowledge base looking for possible mismatching to start corrective procedures. Event expressing errors and specific issues are forwarded to the adaptation and assessment services.
3.4 The Adaptation Service
This fourth design aims at defining and implementing the third agility service. This service should use the analysis of the detection service, as well as the full knowledge base to deduce and suggest adaptation measures that could fit with the current situation and prevent its actual divergence.
3.5 The Assessment Service
This fifth design aims at defining and implementing the fourth agility service. This service is in charge of agility assessment (to bring agility to the agility tools). This task should define relevant KPI and also the way to improve or change the rules and mechanisms of detection and adaptation services.
4 Expected Impacts
By implementing the research framework previously described, this research work should be able to propose a concrete solution to support the collaborative value chain by facilitating the diagnosis of any source of divergence of the collaboration with regard to expected situation. Moreover the project will be able to support the adaptation of the stakeholders’ behaviors by implementing reaction mechanisms based on global and local optimization algorithms. The research work will facilitate the coordination between stakeholders by connecting them efficiently. Particularly, this will eliminate superfluous, inaccurate or irrelevant information regarding the monitoring of the current situation. It will also automate some analysis or actions based on pre-defined business rules in order to support local or global decisions.
The results of the C2NET project will mainly apply to both large enterprises and SMEs in Industry and Non-financial services. Practically, such a contribution should allow increasing drastically the competitiveness of Supply Chains by improving: Consumers’ On Time Delivery, Total Lead-Time, Time-to-Market, Inventories, Carbon footprint, Profitability ratio, Efficiency ratio…
The research leading to these results has received funding from European Community’s H2020 Programme (H2020/2014-2020) under grant agreement n°636909, “Cloud Collaborative Manufacturing Networks (C2NET)”.
