geographic information systems (gis) are one of the fastest growing computer-based technologies of past two decades, yet, full potential of this technology in construction has not been realized. based upon gis capabilities, construction site layout is one of the areas that gis could be applied. the layout of temporary facilities (tfs) such as warehouses, fabrication shops, maintenance shops, co...

Background and Objectives: A sudden jump in blood demand during natural disasters may have strong negative impact on the performance of blood supply chain. Appropriate response to emergency situations requires predictive approach to determining the optimal allocation of blood supply chain resources for various disaster scenarios. The present study, thus, presents an optimization model aimed at ...

This paper introduces a novel approach to enhance the general practice of layout planning of construction sites for producing the efficient utilization. In this work, a solution to the problem is attempted for unequal and irregular temporary facility using robust search and optimization capabilities of Ant Colony Optimization (ACO) algorithm, inspired by the foraging behaviour of real ants. The...

Introduction Safe disposal of nuclear waste is a difficult problem. Long-term plans are to house nuclear waste permanently in underground facilities. In the near-term however, nuclear waste is stored in temporary storage facilities at various sites around the country. Federal and state regulations require periodic inspection of these storage facilities to insure storage vessel integrity and ver...

Introduction Temporary transvenous pacing is routinely used for patients with drug-resistant symptomatic bradycardia complicating acute myocardial infarction. The technique requires skill and facilities which are not always immediately available in district general hospitals. Temporary pacing using an oesophageal electrode is a simple and effective alternative as illustrated by the following ca...

a r t i c l e i n f o Keywords: Actual travel paths Building information modelling (BIM) Construction site layout planning (CSLP) Congested sites Facility dimensions optimization Interior storage Site layout planning is often performed on construction sites to find the best arrangement of temporary facilities so that transportation distances of on-site personnel and equipment are minimized. It ...

This case study of object-oriented program design illustrates two limitations of object-oriented programming languages. Existing object-oriented languages do not have good facilities to support two key program design problems: the definition of composite objects, or data structures that include sets of related subobjects; and the specification and run-time management of temporary data structure...

A construction site represents a conflux of concerns, constantly calling for a broad and multi-criteria approach to solving problems related to site planning and design. As an important part of site planning and design, the objective of site-level facility layout is to allocate appropriate locations and areas for accommodating temporary site-level facilities such as warehouses, job offices, wor...
