There is a large number of literatures about routing and dispatching plans for automated guided vehicle system (AGVS), however a small fraction of these works dealt with dynamic characteristic of this kind of scheduling problems. Current paper surveys a real time strategy to responding requests for supposed material handling system in the plant. We arranged this designing on a preplanned system where all data are known before the constructing routes. An improved ant colony optimization (ACO) is applied in order to find the shortest route path as new solicitations happened. We explore ACO initially for static version of the problem, …
Applying Group Theory For Solving Machines’ Turnovers With Capital Budgeting Approach, Hannaneh Rashidi-Bajgan, Taravatsadat Nehzati, Napsiah Ismail

Applying and utilizing technology in modern manufacturing systems needs to update and upgrade facilities repetitively by efficient ways to stay with great productivity along efficiency. Capital Budgeting Problem (CBP) is one of the most important issues in decision making about capital in manufacturing management; CBP determines the best investments in capital goods such as new plans, replacements, research development projects and other worth pursuing authorization subjects. This problem deals with the amount of revenues as the result of investing in the previous periods in order to maximize the amount of Net Present Value (NPV) on the decision time. Making discussions …

A plant layout study is to analyze different physical configurations for an industrial plant. The warehouse layout problem involves allocating several different product types to certain areas of warehouse so that the cost of material handling from docks of the warehouse can be minimized. The layout of a warehouse may need to be change to accommodate new product lines or to add greater flexibility to the warehouse operations. To ensure the success of the project, a detailed planning process should be followed. Regarding to above Decision Support Systems (DSS) are developed to help company’s personnel, modify the configuration of warehouse …
A Multiobjective Genetic Algorithm For Fuzzy Time Windows Vehicle Routing Problem, Hannaneh Rashidi-Bajgan, Taravatsadat Nehzati
A Multiobjective Genetic Algorithm For Fuzzy Time Windows Vehicle Routing Problem, Hannaneh Rashidi-Bajgan, Taravatsadat Nehzati

Vehicle routing problem (VRP) is a well-known combinatorial optimization problem, holds a central place in logistics management. In the business, transportation, time windows are not always strictly complied and the deviation of service time from specific time window determines the customer’s satisfaction level. The purpose of this paper is to pay about restriction on uploading/delivering time when time constraints are not certain. Therefore this study applies fuzzy membership functions to characterize the service level issues associated with time window violations in VRP with two goals so that minimize the travel cost and maximize the supplier’s service level. In facing to …
A Novel Approach In Determining Points Of Interactive Transportations In The Firm, Zeinab Barati, Hannaneh Rashidi-Bajgan, Elham Esmaili

Partitioning is the most vital element in designing of a firm layout. Today modern working environments are intended to more use of less space which could increase more interactions between related departments. Although progress communications network has reduced the need for physical transportation but the tangible connections between different parts of a firm seems essential still. The firm is willing to reduce transfers to the minimum possible in order to prevent the vain crowd and time stuck. The purpose of this paper is to use a new approach of decision making in the location and layout of firm’s partitions. With …

There are different kinds of jobs in any organization; some of them have more traffic to one another, in the other words there are communicative rates between these office jobs. In this paper we want to develop an approach of analytical hierarchy process (ANP) so that enable us in assigning jobs to suitable office rooms. We suppose that we know distances between places and could predict the amount of flow movements between theses jobs and would like to minimize the distance×flow.
