Dynamic cellular manufacturing systems,   Mixed-integer non-linear programming,   Production planning, Manufacturing attributes   This paper presents a novel mixed-integer non-linear programming model for the design of a dynamic cellular manufacturing system (DCMS) based on production planning (PP) decisions and several manufacturing attributes. Such an integrated DCMS model with an extensi...

With the advent of e-commerce, logistics providers are faced with the challenge of handling fluctuating and sparsely distributed demand, which raises their operational costs significantly. As a result, horizontal cooperation are gaining momentum around the world. One of the major impediments, however, is the lack of stable and fair profit sharing mechanism. In this paper, we address this proble...

A microbiological safety cabinet was evaluated to determine conditions under which microorganisms might escape. Tests were conducted under three cabinet-closure conditions, various airflow velocities, and different laboratory operations, with 10(5), 1.1 x 10(5), and 10(6) microorganisms per cubic foot of cabinet space released per min for 5 min. The data revealed that (i) escape of a human infe...

The abandonment of land, the high energy load generated and accumulated by vegetation covers, climate change and interface scenarios in Mediterranean forest ecosystems are demanding serious attention to forest fire conditions. This is particularly true when dealing with the budget requirements for undertaking protection programs related to the state of current and future forest landscapes. Base...

the objective of this study was to determine the allowed and desired limits for heavy soils of texture (clay loom), as it has operational capability (friability), these limits were 6.34 mm for planting and 10.62 mm for harvesting in each raining or irrigation episode. we determined some factors that affect soil wetness and water content as follow: the amount and severity of rain, the condition ...

A communication network’s reliability, survivability, and interconnectivity are primarily based on the degree of interconnection between the existing nodes of the network. Enhancement of these characteristics can be obtained by adding direct communication links between nodes of the network. This process is generally subject to a budget constraint. From the service provider’s perspective, enhanc...

This article seeks to analyze the allocation of federal government discretionary spending among Brazil’s states. In Brazil, the bulk of federal public budget must be compulsorily executed. Personnel expenditures and social taxes, social security benefits and a series of constitutionally mandatory transfers to states and municipalities are examples of expenditures over which the government has n...

http://iac.dtic.mil/iatac Configuration complexity imposes a heavy burden on both regular users and experienced administrators. This complexity dramatically reduces overall network assurability. For example, a report from the Center for Strategic and International Studies states that “inappropriate or incorrect security configurations were responsible for 80 percent of United States Air Force v...

Excessive project budget overruns is a serious problem that may endanger long-term competitive advantage and financial viability of firms engaged with process development together with equipment suppliers. Joint development of new process technology often span organizational boundaries and are frequently described as both uncertain and equivocal. With the aim to propose better management method...
