Determining a project delivery method that matches the characteristics of construction is critical step affects success or failure project. The Project Delivery Method (PDM) should be adapted to activities and processes implementation. However, traditional selection does not come from internal process which may lead being able meet actual requirements. This research proposes DSM-based PDM frame...

Concurrent engineering (CE) principles have considerably matured over the last decade. However, many companies still face enormous challenges when implementing and managing CE practices. This is due to the increased complexity of engineering products and processes, on one hand, and the lack of corresponding CE models and tools, on the other hand. This paper focuses on four critical problems tha...

Modularity is a concept that is applied to manage complex systems by breaking them down into a set of modules that are interdependent within and independent across the modules. Benefits of modularity are often achieved from module independence that allows for independent development to reduce overall lead time and to reach economies of scale due to sharing similar modules across products in a p...

Modular decomposition is an effective means to achieve a complex system, but that of current part-component-based does not meet the needs of the positive development of the production. Design Structure Matrix (DSM) can simultaneously reflect the sequence, iteration, and feedback information, and express the parallel, sequential, and coupled relationship between DSM elements. This article, a mod...

Wheelchair users with brain-related problems experience involuntary extensor thrusts, which may cause injuries due to unexpected impacts with the wheelchair. An improved wheelchair design would be very beneficial to such users. This paper uses the Design Structure Matrix (DSM), which is an information exchange model that helps find the relationship between tasks in a product development process...

the objective of the present study was to design an oral controlled drug delivery system for sparingly soluble diclofenac sodium (dcl) using guar gum as triple-layer matrix tablets. matrix tablet granules containing 30% (d1), 40% (d2) or 50% (d3) of guar gum were prepared by the conventional wet granulation technique. matrix tablets of diclofenac sodium were prepared by compressing three layers...

Consider a Bayesian optimal design with many support points which poses the problem of collecting data with a few number of observations at each design point. Under such a scenario the asymptotic property of using Fisher information matrix for approximating the covariance matrix of posterior ML estimators might be doubtful. We suggest to use Bhattcharyya matrix in deriving the information matri...
