19、ion system philosophies can be followed through the works presented in this paper. We intend to give software solutions for design, planning and operation (management) of complex, networked organizations represented as nodes of networks. In the first part of the paper, solutions are given to manage

20、complex logistics flows of distributed SMEs, giving more sophisticated solutions than the commonly used supply-chain management (SCM) packages available in the market. The second problem we solve is a complex, web-based solution to manage large, expensive, multi-site, multi-company projects using an

Our goal is to integrate as many available solutions as possible and to make only the appropriate frameworks including decision-support systems where necessary. The first part of the work means the establishment and applicat

These architectures are easy to be integrated if needed, i.e. logistic flows and project management can be solved together.A

The literature findings along with our experience in working with automotive reman products were used asinputs to guide the formulation of seven major propositions for the strategic factors in decision making within reman. The propositions were then tested through a case

39、s limited fossil fuel resources, as well as for reducing the related environmental problems. In this context, waste biomass utilization has emerged as a viable alternative for energy production, encompassing a wide range of potential thermochemical, physicochemical and bio-chemical processes. Two si

40、gnificant bottlenecks that hinder the increased biomass utilization for energy production are the cost and complexity of its logistics operations. In this manuscript, we present a critical synthesis of the relative state-of-the-art literature as this applies to all stakeholders involved in the desig

41、n and management of waste biomass supply chains (WBSCs). We begin by presenting the generic system components and then the unique characteristics of WBSCs that differentiate them from traditional supply chains. We proceed by discussing state-of-the-art energy conversion technologies along with the r

42、esulting classification of all relevant literature. We then recognize the natural hierarchy of the decision-making process for the design and planning of WBSCs and provide a taxonomy of all research efforts as these are mapped on the relevant strategic, tactical and operational levels of the hierarc

However, very few studies address the critical supply chain management issues, and the ones that do that, focus mainly on (i) t

44、he assessment of the potential biomass and (ii) the allocation of biomass collection sites and energy production facilities. Our analysis further allows for the identification of gaps and overlaps in the existing literature, as well as of critical future research areas.Article Outli neIntroductionWa

This paper provides an overview of this formula, and illustrates by means of examples that there are several cases where it is not applicable. Our findings are illustrated with small numer

We finally utilize a new sensitivity solver in the preliminary testing of a simple heuristic for bilevel optimization in continuous traffic network design, and compare it favourably to previous heuristics on known small-scale problems.Articl
