Parallel Conwip for a High-mix Multi-stage Production System with the entrance of rework
Abstract: In a complex production environment, more than one type of pull systems is often used to regulate the processesof different products. In literature, performance studies appertaining to multiple pull systems co-existed in aproduction environment are rare. The present paper evaluates the performances of parallel CONWIP (PC)systems in a high-mix production system with the entrance of rework. The production comprises three stages ofshared-machine facilities. Reject parts produced by the first stage …

An Empirical Analysis of Cost, Time, and Quality Relationships Using Correlation and Regression Techniques
Abstract: Cost, time, and quality have been recognized as the three key dimensions that determine construction project performance and are commonly represented through the "Project Management Triangle." However, despite their theoretical linkage, there is limited empirical evidence to quantify the nature of their relationships, particularly within developing construction markets. This paper seeks to contribute to addressing this shortfall by investigating the specific influence of cost and schedule variations upon quality outcomes …

IS-Aligned Strategic Evaluation of Fire Protection Systems for Improving Fire Safety in Mixed-Occupancy High-Rise Buildings
Abstract: This paper presents a substantially reworked Indian-context evaluation of fire protection systems in a 14-building high-rise sample from Indore. The study reuses the original field dataset but replaces the earlier code mix with an explicitly IS-aligned and NBC-oriented analytical framework. Physical observation, document review and interview inputs were screened against requirements related to means of egress, compartmentation, fire detection and alarm, hydrants and hose reels, extinguishers, emergency lighting, smoke control, …

Ranking of Relative Importance of Productivity Factors in Indian Construction Projects
Abstract: Productivity remains an intriguing subject and a dominant issue in the construction sector. Best performance is unachievable with poor productivity resulting in time over-run and consequently cost escalation of projects. Hence, productivity is of critical importance to the profitability of most construction projects and it is essential that attempts to be made to improve productivity. Any improvement in productivity cannot be achieved without understanding the factors that adversely affect productivity. …

Stakeholder’s Influence on Design-Construction Planning
Abstract: The design phase requires several interactions between the client and the architect as compared to other phases. Major decisions on the project were finalized during this design phase with the inadequate involvement of the forthcoming stakeholders—fabricators, contractors and vendors. Further, fragmentation in design and construction phase had led to redesign and rework during the construction execution. Additionally, this fragmentation had design solutions that had not involved constructability issues, which resulted …

Reformulating Value Added Ratio Using a Construction Job Site Case Study
Abstract: Lean principles have already been successfully implemented in reducing wastage in manufacturing industries such as automobile industry. The present work focuses on application of lean principles at micro level in a quality control lab of a highway project in order to increase the productivity and decrease the proportion of non-value adding time. The total time was broadly categorized into five different categories namely, moving time, waiting time, setup time, process …

Time Overrun Causes in Public Construction Projects in Saudi Arabia: Contractors’ View
Abstract: The time schedule in construction projects is one of the prime measures for project success. However, the construction industry worldwide is full of projects that were completed with significant time overrun. This problem is critical and has negative effects on construction parties in terms of growth in adversarial relationships, mistrust, litigation, arbitration and cash flow problems. This study aims at identifying the time overrun causes in public construction projects in …

Lean Production using Casting Simulation to Promote FTR Approach
Abstract: When the talk is about the green production, then intention is to develop a product with first-time-right approach. Foundry desperately needs such production system, as it provides wide range of products. Even the small errors in the inputs (concept, design, raw material, process, etc.) can lead to wasted outputs [1], and invite unwanted cost of reworking. Thus, it is of extreme importance to develop the castings with FTR (first time …
