In this paper, we consider the problem of optimal placement of a single finite-size, rectangular facility in presence of other rectangular facilities. There is a non-negative interaction between the new and existing facilities as well as pairs of existing facilities. All interactions are serviced through a finite number of input/output points located on the boundary of each facility. We assume ...

This paper presents a facility for definition and management of federated clusters of interrelated information. In a co-working environment, team members need to exchange information in order to coordinate their tasks execution, where typically the information is distributed over several cooperating autonomous systems. The co-working facility described in this paper supports the sharing and exc...

Facility layout planning plays an important role in the manufacturing process and seriously impacts a company’s profitability. A well-planned layout can significantly reduce the total material handling cost. The purpose of this paper is to develop a two-stage inter-cell layout optimization approach by using one of the popular meta-heuristics — the Ant Colony Optimization algorithm. At the first...

Today’s consumer market demands that manufacturers must be competitive. This requires the efficient operation of manufacturing plants and their ability to quickly respond to changes in product mix and demand. In addition, studies show that material handling cost make up between 20 and 50 percent of the total operating cost. Therefore, this paper considers the problem of arranging and rearrangin...

This paper proposes a non-greedy local search heuristic for solving facility layout problem. The proposed heuristic works on non-greedy systematic pair wise exchange of two facilities, that is 2-exchange local search based on non-greedy strategy. Pair wise exchanges are accepted if the objective function value after the exchange is lowered or smaller than the average objective function incremen...

This study sought to develop a typology model of temporary facility constraints that can be used practically in construction site layout planning (CSLP) automation models. A triangulated methodology (literature review, in-depth interviews, and actual case studies) was identify 11 facilities are considered mainly CSLP classify them into six constraint types (i.e., dimensional, regional, relocati...

Since material handling agents in a FMS are most efficient when moving in straight lines, a common layout of machines in a FMS is a single row layout. This allows a floor designer to model the problem of generating an optimal machine layout in a FMS as a single row facility layout problem (SRFLP). Due to the computational complexity involved in solving the SRFLP, researchers have developed seve...

The Android OS consists of a Java stack built on top of a native Linux kernel. A number of recently discovered vulnerabilities suggests that some security issues may be hidden in the interplay between the Java stack and the Linux kernel. We have conducted an empirical security evaluation of the interaction among layers. Our experiments indicate that the Android Security Framework (ASF) does not...

This paper studies a facility location model in which two-dimensional Euclidean space represents the layout of a shop floor. The demand is generated by fixed rectangular-shaped user sites and served by a single supply facility. It is assumed that (i) communication between the supply point and a demand facility occurs at an Input/Output (I/O) point on the demand facility itself (ii) the faciliti...

Safety and performance are important factors in the design and operation of chemical plants. This paper describes the formulation of a mixed integer nonlinear programming model for the optimization of plant layout with safety considerations. The model considers a quantitative risk analysis to take safety into account, and a bowtie analysis is used to identify possible catastrophic outcomes. The...
