This paper aims to determine optimal aggregate production and distribution plans in a supply chain system that simultaneously achieve two business targets of total profit sales, with uncertain parameters, e.g., rate during regular time overtime, inventory holding costs for manufacturer centers, transportation cost. A fuzzy multi-objective linear programming (FMOLP) model is developed represent ...

The design of manufacturing planning and control systems is a strategic decision for manufacturing firms. In this paper we analyze the interrelationships among the choices of planning and control approaches at different hierarchical levels, including sales and operations planning (chase; level), master scheduling (make-to-order; assemble-to-order; make-to-stock), material planning (time-phased;...

This paper presents a discounted cash-flow approach to an inventory model for deteriorating items with the &#10two-parameter Weibull distribution. According to our proposed model, two shortages are considered: back-orders and lost-sales, &#10in which the back-order rate is a varying function of the time when the shortage happens. In general, the demand rate is a linear function of the selling p...
