To reduce the source code complexity, we define a set of conditions for executing the services on a platform of an MDA (model-driven architecture) system. These conditions, which help in correctly executing each service of a system, bridge the gap between the service logic and the interaction part of the system. This paper proposes a system development method based on a service independent interaction model, which is a PIM (platform independent model). A book management system exemplifies the development process based on a service independent interaction model.
In this paper, we discuss the software performance evaluation method considering the real-time property. The dynamic software reliability growth process is described by the Markovian software reliability model with im...

Mobile Ad Hoc Networks are communication networks built up of a collection of mobile devices which can communicate through wireless connections. Mobile Ad Hoc Networks have many challenges such as routing, which is the task of directing data packets from a source node to a given destination. This task is particularly hard in Mobile Ad Hoc Networks: due to the mobility of the network elements and the lack of central control, robustness and adaptability in routing algorithms and work in a decentralized and self organizing way. Through the principles of systems architecting and engineering, the problem statement in Mobile Ad Hoc Networks could be defined more specifically and accurately. The uncertainties and techniques for mitigating and even taking positive advantages of them can be achieved through a framework of uncertainties as in [1]. The systems methodology framework called Total systems Intervention (TSI) described by Flood and Jackson [2] select a systems methodology for Mobile Ad Hoc Networks. The purpose of this paper is to show how TSI when integrated with a framework created to understand the risks and opportunities can help develop strategies to minimize the risks and to take advantage of the opportunities for facing challenges in Mobile Ad Hoc Networks.
We propose a two-dimensional SRGM describing a software reliability growth process on the two-dimensional time-space which consists of testing-time and testing-coverage. Our two-dimensional SRGM conserves the theoreti...

Recent technological developments have revolutionized the design and operation of warehousing systems. Automated storage and retrieval systems (AS/RS) driven by embedded computers are becoming increasingly more prevalent. The increased use of AS/RS is creating the need for computerized control algorithms to support the scheduling and picking decisions. This research addresses an order picking problem in a multi-aisle automated warehouse, in which a single storage/retrieval (S/R) machine performs storage and retrieval operations, and each item can be found in several storage locations. Our objective is to propose algorithms that minimize the total time traveled by the S/R machine to complete the retrieval process of orders. We develop a genetic algorithm and an ordinary heuristic, and provide a performance comparison of them with optimal solution. Numerical results from a large set of problems are reported.

The Japanese concept 'poka yoke', translated into English as 'mistake proofing,' has been mentioned at previous IGLC conferences. This notwithstanding, mistake proofing appears to not have been (nor be) systematically researched or practiced in the lean construction community. To raise awareness of opportunities provided by thinking with mistake proofing in mind as a means to build quality into project delivery, this paper summarizes the philosophy that underlies mistake proofing. Examples illustrate how mistake proofing applies to the work done within one specialty trade, how manufacturers and fabricators can design their products so they cannot be constructed defectively, and how architects and engineers may conceive of system designs that are less likely to fail during construction or in a product's life cycle. Reader contributions to an online repository of mistake proofing applications in the architecture-engineering-construction (AEC) industry, posted at http://***/pokayoke/, will be gratefully acknowledged.
Generally, there are periodic interrupt services such as periodic clock tick interrupts in the real-time embedded systems even though the system is in the idle state. To minimize the power consumption of idle state, p...
