With the advent of newer data services and increase in usage of smart phones, there is an increased demand for data traffic. This puts wireless backhaul operators in catch up mode. To service this increased demand, it becomes critical for operators to maximize spectrum usage and increase capacity for wireless backhaul networks. This paper explains how Shyam's RM Series radio solutions can help ...

The present work addresses an operational inefficiency problem at a semiconductor equipment manufacturing warehouse, Varian Semiconductors Associates and Equipment (VSEA). This problem is important because if unresolved, the warehouse is unable to meet the part delivery time target of 24 hours during the busy period. The downstream effects of the late part delivery are delayed production schedu...

This study assesses the operation efficiency of theme park attractions using the data envelopment analysis, utilizing actual data on 15 attractions at Samsung Everland located in Yongin-si, Republic of Korea. In particular, this study identifies crowding and waiting time as one of the main causes of visitor's satisfaction, and analyzes the efficiency of individual attractions in terms of waitin...

Moving from a paper-based medication management environment to completely on-line processes was a major change for nurses--the largest group of employees and, ultimately, MOE/MAR users. Nursing's involvement and their experiences are analyzed.

The period toward the end of patients' participation in late stage blinded clinical trials is highly resource intensive for the sponsor. Consider first a Phase 3 trial. If the trial is a success, the sponsor has to implement the next steps, which might be filing for approval of the drug with the US Food and Drug Administration (FDA). To shorten the time interval between trial completion and sub...

The last few decades have seen the widespread adoption of large-scale, integrated, packaged software suites collectively called Enterprise Systems. However, most studies done so far have largely focused on the operational efficiency achieved by using these systems. This paper reports on research-in-progress that seeks to explore the strategic potential of Enterprise Systems to enable business t...

Ϫ2 through 10 Ϫ7). The IC was consistently detected in dilutions 10 Ϫ6 through 10 Ϫ9. To determine interassay variation, we assayed 7 clinical samples positive for B. pertussis DNA within the linearity range of the assay 5 times on 5 different days (including reextraction each day). The SD calculated from the crossing points obtained was 0.08 –1.09. We determined in-traassay variation by assayi...

The aim of this paper is to approach the design of distributed layouts for lower work-in-process (WIP) levels. Traditionally, the design of manufacturing layouts has considered as objective the minimization of the material handling cost. Alternatively, distributed layouts are claimed to have good performance under volatile environments, though it has been little investigated how these layouts b...

We consider the activity-based costing situation, in which for each of several comparable operational units, multiple cost drivers generate a single cost pool. Our study focuses on published data from a set of property tax collection offices, called rates departments, for the London metropolitan area. We define what may be called benchmark or most efficient costs per unit of driver. A principle...

Using data on 61 oil companies from 2001-09, we examine the evolution of revenue efficiency of National Oil Companies (NOCs) and shareholder-owned oil companies (SOCs). We find that NOCs generally are less efficient than SOCs, but their efficiency increased faster over the last decade. We also find evidence that partial privatizations increase operational efficiency, and (weaker) evidence that ...
