[ 1 ] - توسعه و حل یک مدل دو هدفه جهت تکمیل توأم موجودی چند کالا با محدودیت فضای انبار
در این تحقیق، یک مدل دو هدفه تکمیل موجودی همزمان چند کالا در حالیکه با محدودیت منابع روبرو هستیم،توسعه داده شده و حل شده است. مدل پیشنهادی دارای یک محدودیت فضای انبار بوده و به دنبال بهینه کردن دو تابع هدف می باشد که عبارتند از مینیمم کردن مجموع هزینه نگهداری و سفارش دهی سالیانه و نیز مینیمم کردن کل سرمایه درگیر در موجودی. در ادامه به توسعه یک الگوریتم ژنتیک چند هدفه برای حل آن پرداخته ایم.به م...
[ 2 ] - A bi-level linear multi-objective decision making model with interval coefficients for supply chain coordination
Abstract: Bi-level programming, a tool for modeling decentralized decisions, consists of the objective(s) of the leader at its first level and that is of the follower at the second level. Three level programming results when second level is itself a bi-level programming. By extending this idea it is possible to define multi-level programs with any number of levels. Supply chain planning problem...
[ 3 ] - کاربرد شبیه سازی تبرید در بهینه سازی یک مدل کنترل موجودی چند محصولی همراه با محدودیت فضا و بازپرسازی تصادفی
In this paper a multi-period inventory control problem will be analyzed. Periodic replenishment will happen totally stochastic and also the periods between two replenishments are independent and identically distributed random variables .indeed producer is encountered with customer in stochastic time. Also the decision variable has been chosen as an integer. In first model shortage will be back...
[ 4 ] - روش جدید کنترل کارت از طریق ترکیب سیاستهای کنترل تولید
One of the efforts in a pull system to meet the final goal of Just-In-Time is reducing Work-In-Process (WIP) without reducing throughput rate an service level. This paper proposes a new hybird control policy using extended Kanban, Generalized Kanban and CONWIP to form the final construction of production plan. Simulation of a 3-stage case study with probabilistic parameters showed the reducti...
[ 5 ] - اندازه‌گیری میزان صرفه‌جویی‌های زمانی حاصل از مشترک‌سازی مولفه‌ها در زنجیره‌های تأمین
Sharing common resources is amongst critical factors creating competitive advantages in business and manufacturing. In today’s competitive and dynamic environment, application of the resource sharing approach has become the focal point of attention for business managers. By resource sharing and through common platform guidelines, the possibility of producing an extended variety of products us...
[ 6 ] - A Mathematical Method for Managing the System Constraint
The goal of theory of constraints (TOC) is to maximize output, which is achieved byidentifying and managing the critically constrained resources. To manage the constraints, Goldrattproposed five focusing steps (5FS). If we increase constrained output, the output of system will beincreased. In this paper, we focus on step four of the 5FS and use the remained capacity of nonconstraintto elevate t...
[ 7 ] - A New Multi-Objective Model for a Cell Formation Problem Considering Machine Utilization and Alternative Process Routes (RESEARCH NOTE)
This paper presents a novel, multi-objective mixed-integer nonlinear programming (MINLP) model for a cell formation problem (CFP) with alternative means. Due to existing contradiction among objectives, three are considered: 1) Minimizing the total cost consisting of; intercellular movements, purchasing, operation, and maintenance; 2) maximizing the utilization of machines in the system; 3) mini...
[ 8 ] - A Holistic Approach Based on MCDM for Solving Location Problems
Location decision is an integral part of organizational strategies involving many factorsthat may be conflicting in nature. This paper presents a holistic approach of the multi-criteria decisionmaking (MCDM) methodology to select the optimal location(s), which fits best for both investors andmanagers. A case study is also provided to illustrate the application of the proposed holistic approach....
[ 9 ] - Two Stage Multiple Attribute Decision Making Problem in Iranian Gas Distribution Systems
The purpose of this paper is to present the possibility of replacing physical unit cost in transportation or distribution problems by an aggregate coefficient, getting qualitative and subjective considerations involved. The model for constructing aggregate cost is a two stage multiple attribute decision-making problems. In the first stage supply points, demand points and routes of transportatio...
[ 10 ] - A new Approach Versus Benders Decomposition in Aggregate Production Planning
This paper proposes a simplified solution procedure to the model presented by Akinc and Roodman. The Benders’ decomposition procedure for analyzing this model has been developed, and its shortcomings have been highlighted. Here, the special nature of the problem is exploited which allowed us to develop a new algorithm through surrogating method. The two methods are compared by several numerical...
[ 11 ] - Bus Assignment to Iranian Pilgrims During Pilgrimage
Among the multitude of activities of Hajj Organization which require careful planning bus assignment to the Iranian pilgrim caravans d g pilgrimage is the most important one. The objective of this assignment is to have a minimum number o standing passengers/empty seats, while satisfying a large number of operational and religious constrain. This problem was formulated as a large scale zero-one ...
[ 12 ] - A Partially Observable Markovian Maintenance Process with Continuous Cost Functions
In this paper a two-state Markovian maintenance process where the true state is unknown will be considered. The operating cost per period is a continuous random variable which depends on the state of the process. If investigation cost is incurred at the beginning of any period, the system wit I be returned to the "in-control" state instantaneously. This problem is solved using the average crite...
