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

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 …

Toward A Theoretical Concept Of E-Collaboration Through Project Management In Smes For Reducing Time And Cost In New Product: A Review, Marjan Mohammadjafari, Siti Zawiah Md Dawa, Shamsuddin Ahmed, Hadi Zayandehroodi

Dr. Marjan Mohammadjafari

Reducing time and efficient project execution is an objective in many industries and project management is one of the important keys for lead the company to this allegation. The project manager needs some tools for lead the firm to the success. Collaboration is one way to success and collaboration has many types, one kind is electronic collaboration. On the other hand, small and Medium Size Enterprises (SMEs) are a part of manufacturing industries. Combining a literature review with our empirical experience we found that relationship between the project manager and related departments for production is essential for reducing time and …

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 …

An Integrated Model For A Two-Supplier Supply Chain With Uncertainty In The Supply, Mehdi Sajadifar

university of science & culture

The objective of this paper is to study an integrated two-supplier supply chain whose suppliers are unreliable. An unreliable supplier is alternative between available (ON) and unavailable (OFF) states which are considered to be independent exponential variables. The suppliers apply a continuous review policy and the retailer uses an adapted continuous review base on an(R,Q) policy. Transportation times are constant and lead times are non-zero random variables. The retailer faces independent Poisson demands. Using the idea of the one-for-one ordering policy, we implicitly incorporate the distribution function of the random delay for obtaining the value of the expected costs of …

An Overview Of Technologies For Upgrading Of Biogas To Biomethane, Wojciech M. Budzianowski

Wojciech Budzianowski

The present contribution presents an overview of technologies available for upgrading of biogas to biomethane. Technologies under study include pressure swing adsorption (PSA), high-pressure water wash (HPWW), reactive absorption (RA), physical absorption (PA), membrane separation (MS) and cryogenic separation (CS).

Influence Of Energy Policy On The Rate Of Implementation Of Biogas Power Plants In Germany During The 2001-2010 Decade, Izabela Chasiak, Wojciech M. Budzianowski

Wojciech Budzianowski

The current article describes energy policy tools, which caused intensive development of biogas-based power generation in Germany during the 2001-2010 decade. The German system of financial support to biogas power plants is presented in details. It is shown that in Germany, i.e. in a country characterised by similar climate and potentials to renewable energy to Poland, biogas power plants cover 10,7% of electricity demands in 2010, while all renewable energy sources cover only 5,4% of electricity demands. It is emphasised that under favourable Polish energy policy, the development of biogas energy can be very rapid.

Kernel Regression In The Presence Of Correlated Errors, Kris De Brabanter, Jos De Brabanter, Johan A.K. Suykens, Bart De Moor

Kris De Brabanter

It is a well-known problem that obtaining a correct bandwidth and/or smoothing parameter in nonparametric regression is difficult in the presence of correlated errors. There exist a wide variety of methods coping with this problem, but they all critically depend on a tuning procedure which requires accurate information about the correlation structure. We propose a bandwidth selection procedure based on bimodal kernels which successfully removes the correlation without requiring any prior knowledge about its structure and its parameters. Further, we show that the form of the kernel is very important when errors are correlated which is in contrast to the …

Understanding Student Pathways In Context-Rich Problems, Pavlo Antonenko, John Jackman, Piyamart Kumsaikaew, Rahul Marathe, Dale Niederhauser, Craig Ogilvie, Sarah Ryan

Sarah M. Ryan

In this paper we investigate the ways that students' problem-solving behaviors evolve when solving multi-faceted, context-rich problems within a structured, computer-based learning environment. During the semester, groups of two or three students worked on several problems that required drawing on more than one concept and, hence, could not be readily solved with simple "plug-and-chug" strategies. The problems were presented to students in a data-rich, online problem-solving environment that tracked which information items were selected by students as they attempted to solve the problem. The students also completed a variety of tasks, like entering an initial qualitative analysis into an online …

Evaluating The Impact Of Patient Arrival Patterns In The Performance Of Appointment Scheduling Rules, Alcides Santander-Mercado, Jose Zayas-Castro, Laila Cure, Ali Yalcin

Laila Cure

This paper evaluates the ability of commonly used Appointment Scheduling Rules (ASRs) in smoothing the effect of environmental factors in the performance of an outpatient scheduling system. ASRs have been widely implemented in outpatient clinics to improve performance measures such as staff idle time, patient waiting time, and facility congestion. However, the successful implementation of an ASR depends on its ability in dealing with the environmental factors affecting the system. Factors such as no-shows, variability of consultation times, patient unpunctuality, walk-in patient arrivals and the number of admitted patients per session affect the performance of the clinics in terms of …
