Simulation modelling and Lean principles have both been applied in the construction industry to improve work processes. The outcomes from their implementation are outstanding and have motivated construction researchers to seek means by which other aspects of construction production could benefit from this development. Therefore the aim of this research is to use computer simulation as a tool fo...

Through literature review and drawing from a combined professional experience of over 20 years of lean construction implementation, this paper investigates the key success factor for the automotive industry’s uptake of lean production to see what the construction industry can derive from it. The paper concludes that there exist a variety of definitions of lean, but no existing definition is yet...

The objective of this study was to cross-calibrate measurements of body composition by dual-energy X-ray absorptiometry (DXA) with chemical analysis of carcasses of pigs in the pediatric range of body weight. Eighteen pigs (25.5 +/- 7.0 kg; 9.9-32.8% body fat) were scanned in duplicate by using DXA with a Lunar DPX-L densitometer in the pediatric medium and adult fast-detail scan modes. Pigs we...

To gain the full benefit from this new business strategy, it must be fully embraced by top management. It is also important to understand that this concept may be more accurately described as lean thinking instead of lean production. Using the “lean thinking” terminology ensures that the concept is viewed as a total business model, including product development, design and sales. Lean thinking ...

Since they were first developed, lean methodologies have grown in importance and scope and have been applied in both manufacturing and service. However, determining how to transform a common manufacturing company into a lean one, as well as how to evaluate the future company, are challenges for both researchers and manufacturers. This paper presents a case study of a lean manufacturing implemen...

A traditional lean transformation process does not validate the future state before implementation, relying instead on a series of iterations to modify the system until performance is satisfactory. An enhanced lean process that includes future state validation before implementation is presented. Simulation modeling and experimentation is proposed as the primary validation tool. Simulation model...

Much attention has been placed on measuring performance of activity completion in Lean literature, using techniques such as Percentage of Planned Activities Completed (PPC). Originally intended as one component of measuring plan execution, along with measures of Planned Productivity, PPC has been extensively researched but Planned Productivity has been neglected. Using a lean methodology based ...
