This paper considers a multi-echelon, non-cooperative and competitive decentralized supply chain (SC) network consisting of multiple entities. The independent and disjointed entities of a decentralized SC face a major challenge in coordination and maintaining sustainability across its chain. This problem environment is not suitable with traditional...

In this paper, a multistage decentralized supply chain (SC) with different independent entities is modeled with the combination of centralized and decentralized decision-making processes. To do so, mathematical models are developed, based on the concepts of bilevel programming and the weighted goal programming approach. Here, a strategy of centrali...

Human resource performance appraisal is a formal management system that provides for the evaluation of the quality of an individual’s performance in an organization towards achieving organization goals by increasing the abilities, merits and growth of personnel. It is an element of group decision making model in which personnel are evaluated from d...

Fresh light has been shone on the problem of digital inequality (DI) in recent years due to its expanding complexity and impact on society. An issue with DI research is the need for more reliable instruments to measure and gauge the DI status quo, which is critical for appropriate remedial measures and solutions. DI has several dimensions beyond tr...

Coordinating various activities among company members facing real-life uncertainties or disruptions is a great issue of concern in today’s business world. With this background, a multi-stage decentralised supply chain (SC) network is studied in this paper, where demand uncertainties are considered in each stage of the chain. We consider a serial SC...

COVID-19 has posed many unique and critical challenges in various contexts and circumstances. This often led the stakeholders and decision-makers to depart from traditional thinking and the business-as-usual processes and to come up with innovative approaches to tackle various mission-critical situations within a short time frame. In this paper, a...

In this paper, a multi-echelon, multi-period, decentralized supply chain (SC) with a single manufacturer, single distributor and single retailer is considered. For this setting, a two-phase planning approach combining centralized and decentralized decision-making processes is proposed, in which the first-phase planning is a coordinated centralized...

Synchronisation among supply chain (SC) stages is essential, but difficult to achieve, which results in a bullwhip effect. This paper proposes an interactive fuzzy-based genetic algorithm approach for reducing bullwhip effect by minimising total SC cost as well as to determine optimal ordering quantities in a multi-stage, multi-period SC using fuzz...

Inventories are raw materials, work in process and completely finished goods that are considered to be the portion of business's assets that are ready or will be ready for sale. Formulating a suitable inventory model is one of the major concerns for an industry. Numerous researches have been done on the inventory models both for the deterministic a...

It is always a great challenge to select an optimal route in case of a complex supply chain architecture. The challenge lies in meeting the reverse condition of quality of service and money. As time is an important factor, choosing the optimal route in supply chain architecture often becomes the most vital. To automate the route finding, in this pa...

Choosing the appropriate inventory or material control strategy is a key factor for the success of modern enterprises. Material classification problem in inventory exists to stock physical goods or commodities for the purpose of satisfying demand over a specified time horizon. The paper deals with the case of companies facing the problem of managin...
