literature proves the importance of the process role in the effectiveness of virtual research and development (R&D) teams for new product development (NPD). However, the factors that make process construct in a virtual R&D team are still unclear. The manager of virtual R&D teams for NPD does not know which items of process should be used. To address the gap and answer the question, the study presents a set of factors that make a process construct. The proposed construct modified by finding of the field survey. We empirically examine the relationship between construct, dimensions and its factors by employing the …

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
Dr. Marjan Mohammadjafari
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 …

A Theoretical Research Framework For Sharing Knowledge Through E-Collaboration, Marjan Mohammadjafari Dr, Shamsuddin Ahmed, Siti Zawiah Md, Hadi Zayandehroodi
Dr. Marjan Mohammadjafari
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, …

A Multiobjective Genetic Algorithm For Fuzzy Time Windows Vehicle Routing Problem, Hannaneh Rashidi-Bajgan, Taravatsadat Nehzati
Hannaneh Rashidi-Bajgan
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.

Virtual Integration As A Predictor For Product Innovation: A Preliminary Insight, Geraldy Dadriyansyah, Amlus Ibrahim
Geraldy Dadriyansyah
The intense competition in manufacturing industry has forced manufacturing firms to switch their product development approach from traditional to concurrent engineering in order to stay competitive in term of product differentiation and innovation. In order to support concurrent engineering practice, both internal and external participants contributing to product development should be located into close proximity; therefore physical integration of team becomes the key enabler of concurrent engineering. However, as the paradigm has been shifted from adopting “centralized integrated product development”, physical integration is no longer efficient and should be replaced by virtual integration. This conceptual paper intends to explore ways …

The Information area has revolutionized the workplace. Douglas Kruse, a professor of human resources and the director of the program for disability research at Rutgers University, states that 7% of employed persons with disabilities work 20 hours or more a week from home. While some modern countries have established “virtual teams”, which are said to be comprised of people who are geographically scattered and who work across boundaries of space and time using computer driven communication technologies, it is also true that many developing countries remain structured around conventional face-to-face teams. A motive toward virtual team working may be cost …
