Based on credibility theory and two-stage fuzzy optimization method, this paper presents a type of multi-product multi-period (MPMP) production planning model. Since the proposed production planning problem includes fuzzy variable coefficients with an infinite support, it is infinite-dimensional optimization problem. The approximation of the production planning problem is discussed, and the con...

on time supply of materials in construction projects is very important. therefore, coordinating a project with key suppliers, while ensuring the timely supply of materials, make the minimum costs of project. one way to create this coordination is integrated inventory planning which has been accomplished in this study. it is necessary to mention that such a model is considered np_hard in terms o...

Production costs in general, and workforce and inventory costs in particular, constitute a large fraction of the operating costs of many manufacturing plants. We introduce cooperative aggregate production planning as a way to decrease these costs. That is, when production planning of two or more facilities (plants) is integrated, they can interchange workforce and products inventory; thus, thei...

A planning board is a planning tool that uses the Gantt chart as its main representation mechanism. A planning board generator aims at facilitating the development of planning boards; using a description of the problem type for which a planning board is to be developed and the desired representations and manipulations, the generator automatically creates a prototype of the planning board. In th...

A planning problem is time-dependent, if the time spent planning affects the uti l i ty of the system's performance. In [Dean and Boddy, 1988], we define a framework for constructing solutions to time-dependent planning problems, called expectation-driven iterative refinement. In this paper, we analyze and solve a moderately complex time-dependent planning problem involving path planning for a ...

This paper focuses on formulating capacity-price trade off problem in Yield Management for manufactur-ing industry by drawing motivation from the remarkable success of Yield Management (YM) implementation in airlines. In the current practice, there is no alternative and procedure for the manufacturer, as well as cus-tomers to take advantage of using the unfulfilled capacity in discounted offers...

This paper proposes an advanced distribution automation planning problem in which emergency-based demand response plans are incorporated during service restoration process. The fitness function of this planning problem consists of various costs associated with fault occurrence in electric distribution systems consisting of the total yearly cost of customers’ interruptions, the total annualized ...

This paper presents an application of Benders decomposition to deal with the complexities in the simultaneous Generation Expansion Planning (GEP) and Transmission Expansion Planning (TEP). Unlike the power system operation fields of study, the power system planning methods are not expected to be fast. However, it is always preferable to speed up computations to provide more analysis options for...
