Risk Management Plan in Large Urban Projects
One of the risks distinguishes urban projects from other projects is to purchase of property obstacles. The matter is of more significance in large projects. Issues with regard to possessing property obstacles, lack of accurate layout drawings for underground facilities and following probable changes in designs make it vital to have specific studies on risk management of such projects. So thi...

متن کاملInvestigating Factors Affecting Urban Growth of Large Cities in Iran
The present paper focuses on determining the most important factors affecting urban growth in large cities of Iran through modeling and comparing the common and diverse points of urban growth obtained from other studies. For this purpose, by reviewing the theoretical concepts associated with urban growth, quantities and measurable variables are developed as proper frameworks to study the influe...
متن کاملDimensioning Large Call Centers
We develop a framework for asymptotic optimization of a queueing system. The motivation is the staffing problem of large call centers, which we have modeled as M/M/N queues with N , the number of agents, being large. Within our framework, we determine the asymptotically optimal staffing level N ∗ that trades off agents’ costs with service quality: the higher the latter, the more expensive is th...
متن کاملPulmonary tuberculosis among health care workers at two designated DOTS Centers in urban city of Ibadan, Nigeria
BACKGROUND & OBJECTIVES Tuberculosis (TB) infection control interventions are not routinely implemented in many Sub-Saharan African countries including Nigeria. This study was carried out to ascertain the magnitude of occupationally-acquired pulmonary TB (PTB) among health care workers (HCWs) at two designated DOTS centers in Ibadan, Nigeria. METHODS One year descriptive study (January-Decemb...
