Electronic Collaboration And Project Management To Develop A Conceptual Model, Marjan Mohammadjafari Dr, Shamsuddin Ahmed, Siti Zawiah Md, Hadi Zayandehroodi
Electronic Collaboration And Project Management To Develop A Conceptual Model, Marjan Mohammadjafari Dr, Shamsuddin Ahmed, Siti Zawiah Md, Hadi Zayandehroodi
Dr. Marjan Mohammadjafari
The use of electronic collaboration (E-collaboration) technologies is important for supporting distributed projects. E-collaboration has the potential of networking and collaborative technologies to support the project management teams in the creation of shared understanding. E-collaboration fosters new kinds of collective work made possible with advanced collaboration technologies. On the other hand, project management has been considered as an academic field for planning, organizing, controlling to producing products with predictable cost, time and quality and, in other applications of engineering requirements. A conceptual relationship between project management and E-collaboration can play a vital role in addressing many problems among the participating …
A Review Of Literature On Reducing Time And Cost Of New Product In Smes Through Project Management By E-Collaboration, Marjan Mohammadjafari Dr, Shamsuddin Ahmed, Siti Zawiah Md, Hadi Zayandehroodi

Efficient project execution is an objective in many industries, and existing project management research gives direction about how project team factors influence two important capital project outcomes: time and cost. In addition, use of electronic collaboration (E-collaboration) technologies is essential for supporting projects. Combining a literature review with our empirical experience, we constructed a theoretically based, four-dimensional model of department of design, department of planning, department of production and department of procurement. One major practical implication of our findings is that relationship between project manager and four noted departments by E-collaboration is vital for reduce time and cost in small …

In the backdrop of rapid changing of product features and varieties, on-time data and information exchange between the departments of a manufacturing company has become inevitable. In case of large or multi-national companies (MNCs), information exchange between the geographically dispersed units might be time consuming, less effective, and in turns more costly than expected. Such environments need to use the modern offers. Electronic collaboration (E-collaboration) offers quick and less costly approach. E-collaboration is a means for sharing knowledge data, and information between different departments within a company or ease reaching out to other companies as well. E-collaboration can create a …

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 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 …
Developing Spreadsheet Based Decision Support System To Solve Warehouse Layout Problem, Taravatsadat Nehzati, Napsiah Ismail, Hannaneh Rashidi-Bajgan
Developing Spreadsheet Based Decision Support System To Solve Warehouse Layout Problem, Taravatsadat Nehzati, Napsiah Ismail, Hannaneh Rashidi-Bajgan

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 …

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.
