[00898] An inventory model for the impact of supply chain interruptions during the covid-19 crisis

  • Session Date & Time : 3C (Aug.23, 13:20-15:00)
  • Type : Contributed Talk
  • Abstract : The research work is about minimizing the total cost of a two-warehouse system during the lock-down period. The LIFO policy has been used in this model. In the first scenario, the stocks of the rented warehouse (RW) become empty after the lock-down eased, and in the second scenario, the stocks of the RW become empty during the lock-down. Here, two parametric Weibull distributions for the deterioration rate and a time-dependent demand are taken into consideration.

[01607] AN INVENTORY MODEL WITH PRICE- AND STOCK-DEPENDENT DEMAND

  • Session Date & Time : 3C (Aug.23, 13:20-15:00)
  • Type : Contributed Talk
  • Abstract : In this paper, we develop a multi-item inventory model with price- and stock-dependent demand and backorder. The decision variables in the model are the cycle length and the time when inventory drops to zero. The purpose of the model is minimizing the total inventory cost. Comparisons among alternative replenishment policies such as individual order, joint order or combination between these two policies are also considered. Numerical experiments and sensitivity analysis are also given.

[02564] Supplier selection for returnable packaging products under a supply chain

  • Session Date & Time : 3C (Aug.23, 13:20-15:00)
  • Type : Contributed Talk
  • Abstract : A manufacturer produces a returnable multi-use packaging product, and the retailer uses it for delivering ordered products to customers. Customers return the packaging product, and the retailer uses the packaging product again. The manufacturer has multiple raw material suppliers for semi-finished products. This research develops a decision support system for supplier selection of multi-use packaging products under closed-loop supply chain management. Mathematical modelling of supplier selection for selecting desirable suppliers is solved using game theory.

[00224] Multi-objective multi-route STP with carbon emission and risk mitigation in Pharmaceutical Supply Chain under Pythagorean fuzzy Environment

  • Session Date & Time : 3C (Aug.23, 13:20-15:00)
  • Type : Industrial Contributed Talk
  • Abstract : This research proposes multi-objective multi-route fixed-charge solid transportation problem with carbon emission and risk mitigation in Pharmaceutical Supply Chain (PSC) under trapezoidal Pythagorean fuzzy environment. A novel ranking index is proposed to convert the suggested Pythagorean fuzzy model into its deterministic version. This study develops new computational procedure to minimize the chosen factors in PSC. Thereafter the model is solved by intuitionistic fuzzy and hybrid programming. Finally, an example is included to show the effectiveness of the model.

[00293] Reverse supply chain design and planning in a Mean-Risk framework

  • Session Date & Time : 3C (Aug.23, 13:20-15:00)
  • Type : Contributed Talk
  • Abstract : In this paper, we determine the supply chain structure together with the planning decisions that optimize simultaneously the net present value in the presence of uncertain parameters. The model considers all main supply chains operations. The novelty of this paper is the model for the design and planning of supply chains with the simultaneous consideration of the reverse logistics activities, operational risk induced by the uncertainty of products demands, and decision maker’s loss-aversion.
