This paper addresses the problem of making supply chain operation decisions for refineries under two types of uncertainties: demand uncertainty and incomplete information shared with suppliers and transport companies. Most of the literature only focus on one uncertainty or treat more uncertainties identically. However, we note that refineries have more power to control uncertainties in procurem...

the study determined optimum inventory levels for various bakery resources using the bread supply chain network in onitsha city. structured questionnaires were administered among bakery factories. the optimum design achieved through the optimization model was compared with the existing systems. analysis of 90 bakeries with a combined capacity of 3960 revealed that total money n 564,408,477.28 i...

For firms in an oligopoly service network, demand learning based dynamics pricing is an efficient way to maximize their revenues. This paper introduces a Bayesian method to learn demand behavior from the perspective of game-theoretic dynamics, where non-parametric techniques for nonlinear time series are incorporated, such that stringent parametric assumptions are removed. We determine the unkn...

In response to significant disruption, supply chain optimization became sensitive increasing consumer expectations, unexpected demand fluctuation, and inventory costs. Proactive movement, understanding, empowerment have fostered the beneficial results of optimization, cooperation, operational resilience. These pioneering activities are critical achieving a paradigm shift in chain, even agility ...

T life cycle of new products is becoming shorter and shorter in all markets. For electronic products, life cycles are measured in units of months, with 6to 12-month life cycles being common. Given these short product life cycles, product demand is increasingly difficult to forecast. Furthermore, demand is never really stationary because the demand rate evolves over the life of the product. In t...

One of the most important things in pursuit of supply chain management is to prevent sub-optimization caused by decentralized decision making over the various entities. As a solution of the issue, supply chain coordination approach has frequently been used. However, a coordinated supply chain might fail to provide additional profit to one of the players. A supply chain contract can be to achiev...

The revenue management concept and techniques are applied to model the coordination of supply chain elements. The fundamental premise of this approach is synchronization of a group of business entities consist-ing of a manufacturer and multiple suppliers to achieve an optimal supply chain capacity plans. The output of the supply chain can be various products and thus it is measured in terms of ...

Highlights: A manufacturing supply chain dealing with decaying inventory is studied three production sub-cycles. Price-based demand, the Weibull degradation rate and carbon tax policy are taken into account. Price, emission factor, cycle length period decision variables to increase profit. Goal: The research work aims maximize profit for a deteriorating inventories. To profit, optimum value of ...

In this paper, a bi-level game-theoretic model is proposed to investigate the effects of governmental financial intervention on green supply chain. This problem is formulated as a bi-level program for a green supply chain that produces various products with different environmental pollution levels. The problem is also regard uncertainties in market demand and sale price of raw materials and pro...
