Sustainable Agri-Food Supply Chain with Uncertain Demand and Lead Time

Lead Time Demand Modeling in Continuous Review Supply Chain Models

This paper introduces a mixture distribution approach to modeling the probability density function for lead time demand (LTD) in problems where a continuous review inventory system is implemented. The method differs from the typical “moment-matching” approach by focusing on building up an accurate, closed-form approximation to the LTD distribution from its components by using mixtures of trunca...

An Integrated Production-Supply System with Uncertain Demand, Nonlinear Lead Time and Allowable Shortages

A supply chain consisting of a single-supplier and a single-buyer is modeled and compared in two different modes: non-coordinated and coordinated. The model is established based on the fact that the demand is uncertain and shortages are considered as lost sales. The buyer’s order lead time is a nonlinear function of the buyer’s order size and the number of shipments from the supplier. Quantity ...

Two-stage Supply Chain Model with Uncertain Demand

Based on uncertainty theory, a twostage supply chain model is presented, where the customers’ demands are characterized as uncertain variables. The objective is to minimize the combined costs incurred in the manufacturing and logistics phases. When these uncertain variables are linear, the objective function and constraints can be converted into crisp equivalents, then can be solved by traditio...

Development of Holistic Framework Incorporating Collaboration, Supply-Demand Synchronization, Traceability and Vertical Integration in Agri-Food Supply Chain

Successful implementation of food supply chains in improving the productivity and operational efficiency by some companies made many other firms and researchers courteous about this fast developing field. For successful strategies, organizations in agri-food business are aiming to bring all its stakeholders in close cooperation. The agri-food supply chain aims at optimal warehousing and locatio...
