Abstract
Purpose: This study aim to examine the roots of professional resistance of procurement in Iran. Public procurement (PP) contracts, in developing countries, hide the structural problems of governmental management because of the lack of bureaucratic processes. Design/methodology/approach: A two-phase qualitative study offers contextual and critical understandings on why Iranian PP experts, who are aware of the philosophies behind internationally endorsed principles, prefer to resist against the use of those principles. They help, unexpectedly, their traditionalist companions to resolve the difficulties of the PP contracts by the use of local methods and routines. Findings: Evidence, from...

Abstract
A cooperative supply chain seeks to coordinate its members to produce and distribute products along the chain, for minimum overall costs to satisfy customer demand. An integrated multi-period, multiple product and multiple stage supply chain is formulated using a flow networks framework. A Cooperative Supply Chain Optimizer (CSCO), as a central software entity taking advantage of Grid technology, connects and gathers necessary operational information from members of the corporate supply chain. The CSCO then guides supply chain members on ordering decisions, for a minimum overall cost of the entire supply chain, while continuously re-directing the members as new data becomes available. The...

Abstract
A collaborative supply chain seeks to coordinate its members to produce and distribute products along the chain for minimum overall costs to satisfy customer demand. An integrated multi-period, multi-product and multi-stage supply chain model is developed. A collaborative supply chain grid (CSCG) system gathers necessary information on operations and resources from members of the supply chain. It then guides the members on ordering decisions for a minimum overall cost, while continuously re-directing them as new data becomes available. An actual CSCG system has been implemented in a collaborative auto industry with diverse and dynamic membership, yielding an approximately 26% reduction in...
Cost and inventory benefits of cooperation in multi-period and multi-product supply
, Article Scientia Iranica ; Volume 18, Issue 3 E , 2011 , Pages 731-741 ; 10263098 (ISSN) ; Sharif University of Technology
2011
Abstract
Cooperation among supply chain members, both horizontally and vertically, has become the norm in practice. Unlike traditional supply chains with members competing to reduce their individual costs, the overall cost of the entire supply chain is minimized in a cooperative supply chain. The savings from cooperation may be shared among the members, while a lower average cost and a lower cost variation is materialized for individual members. The problem is formulated as an integrated flow network and expanded to multi-period and multi-product, with the possibility of holding inventories in a multi-stage, multi-member cooperative supply chain. Simulation results indicate an approximately 26%...
Lesson learned knowledge in project management
, Article Science and Information Conference, SAI 2015, 28 July 2015 through 30 July 2015 ; July , 2015 , Pages 949-953 ; 9781479985470 (ISBN) ; Sharif University of Technology

Abstract
Every project is temporary and unique in nature. However, knowledge and lessons learned in projects may be used in other projects to improve the project management services. A learned lesson comes from past and current projects, captured through well-defined organizational processes. It aims to capture an essence of an experience which may be utilized to modify the project processes, or the situations for which that lesson applies. Although lessons learned is used in many industries and is an essential part of Project Management Body of Knowledge, no effective process has been defined to capture, validate, and reuse projects' lessons learned. A three stage system was developed and used to...
Analysis of time delays in projects - application to Iran and emerging countries
, Article 2006 IEEE International Conference on Management of Innovation and Technology, ICMIT 2006, Singapore, 21 June 2006 through 23 June 2006 ; Volume 2 , 2006 , Pages 681-684 ; 1424401488 (ISBN); 9781424401482 (ISBN) ; Sharif University of Technology

Abstract
Numerous projects are underway in emerging countries, such as Iran, where technology transfer and economic expansion are the primary national objectives. However, majority of these projects either fall, according to world class standards, or faced with significant time delays. An Initial analysis of selected projects reveals that over 60% of causes belong to organization factors, while environment and personal causes are less than 40%. The overwhelming evidence points of lack of proper project management and education within organization factors. Some prescriptive interventions are proposed to counter organization deficiencies and overcome consistent time delays. A planning stage using...

Abstract
There is limited research that considers the sustainability aspect of the projects’ schedule. The present study proposes a model to cover this gap by considering sustainable development criteria. A multi-objective model with four objective functions, including minimizing cost, risk, and socio-environmental impacts, has been presented to decrease the project’s delay. Since some of the parameters are considered under conditions of uncertainty for the proximity of problems to real projects, the robust programming method is used to deal with the uncertainty, and the epsilon-constraint method was applied to solve the multi-objective model. Several scenarios are also defined to analyze the...
A quantitative examination of competition, coopetition and cooperation in supply chains
, Article South African Journal of Business Management ; Volume 42, Issue 3 , 2011 , Pages 61-70 ; 03789098 (ISSN) ; Fayazbakhsh, K ; Sharif University of Technology
2011
Abstract
Traditionally, the members of a supply chain compete to reduce their individual costs. However, as collaborative supply chain approach is urged within industries to reduce the overall costs, either full cooperation or partial coopetition is considered by the members. In cooperative approach, members benefit from lower overall costs and lower cost variations. But individually, some seem better off in a competitive approach in a single period considering their local costs. Coopetition, or partial cooperation, may be suggested as a compromise to lower overall supply chain costs, while members choose alliances towards lower average costs and cost variations. A multi-stage, multi-member,...
A multi-period and multi-product optimizer for cooperative supply chains
, Article South African Journal of Business Management ; Volume 43, Issue 1 , 2012 , Pages 77-92 ; 03789098 (ISSN) ; Fayazbakhsh, K ; Sharif University of Technology
2012
Abstract
Members in a traditional supply chain compete to reduce their individual costs. But total cost is minimized in a cooperative, or a corporate managed, supply chain. A lower average cost and a lower cost variation are achieved by cooperative individual members in the long-run. The problem is formulated and solved as an integrated flow network. Previous research is expanded to include multi-period and multi-product cooperative supply chain with possibility of holding inventory in a multi-stage, multi-member setup. A Cooperative Supply Optimizer System (CSOS), a software-based coordination mechanism, is developed for large chains. It gathers operational information from members of the supply...

Abstract
Supply chain sustainability, with economic, environmental, and social values, has gained attention in both academia and industry. For deteriorating and seasonal products, like fresh produce, the issues of timely supply and disposal of the deteriorated products are of great concern. This paper is to develop a possibilistic mathematical model, solved after linearizing the non-linear statements, and to propose a new replenishment policy for a centralized Sustainable Supply Chain (SSC) for deteriorating items. Different transportation vehicle options, which produce various pollution and greenhouse gas (GHG) levels, are considered. Several variables such as the end-customer demand, the partial...
Risk Breakdown Structure (RBS) Identification and Designing for projects
, M.Sc. Thesis Sharif University of Technology ; Sepehri, Mehran (Supervisor)
Abstract
To actualize and making the outputs of a project effectual, it is necessary to conduct an effective management during a project. This case may not be possible without accurately planning for activities, management and controlling all phases of a project ignoring the risk management of that project. If risks of a project cannot be detected before conducting a project, it is possible to challenge the performance and even effectiveness of the project. In current conditions, the most important problem of managers and executives of construction projects through the country is risk management of projects, not acknowledging with definitions of risk, models of risk management and lack of a model for...

Exploratory and Explanatory Research on Corruption in Public Procurement. A multiple Case Study in Four Subsidiaries of NIORDC
, Ph.D. Dissertation Sharif University of Technology ; Sepehri, Mehran (Supervisor)
Abstract
Despite a rather long history of bureaucratic public administration, Iranian public sector has failed to catch up with the ever developing knowledge of fighting corruption in “public procurement”, a critical field of governmental management which accounts for at least 15 percent of GDP around the world. While international organizations like TI and OECD have been broadly active in globalizing the standards of integrity and calling for improvements in the national frameworks of procurement, a reductionist agenda might take the safest path of change by following whatever prescribed by those international bodies. However, there have also been some deeper reflections on the complexities of...
