In this paper, the problem of management in an organization with a hierarchical structure is modeled as a hybrid multi-layer switching control problem. A novel approach is proposed to transfer a management problem to a control system problem. the supervisory control of a Discrete-Event System (DES) is used for decision making in the organization. This method takes advantage of the hierarchical structure of an organization to find the optimal solution in terms of achieving the desired scopes of the project while minimizing the resources (time and cost). Although the problem formulation is explained for a hierarchical organization, the method is general enough to be applied to any team collaboration problem including the flat structure organizations. In fact, this methodology improves the monitoring and controlling phase of the project management.

This paper presents a scheduling heuristic to minimize the makespan of a re-entrant flow shop using bottleneck analysis. The heuristic is specifically intended for the cyber manufacturing centre (CMC) which is an Internet-based collaborative design and manufacturing between the Universiti Tun Hussein Onn Malaysia and the small and medium enterprises. The CMC processes scheduling resembles a four machine permutation re-entrant flow shop with the process routing of M1,M2,M3,M4,M3,M4 in which the first process at M1 has high tendency of exhibiting dominant characteristic. It was shown that using bottleneck-based analysis, an effective constructive heuristic can be developed to solve for near-optimal scheduling sequence. At strong machine dominance level and medium to high job numbers, this heuristic shows slightly better makespan performance compared to the NEH. However, for smaller job numbers, NEH is superior.

This paper focuses on energy management problem applied to residential sector. The optimizing procedure of energy management is based on the available prediction (weather prediction, user¿s habit etc) which contains the uncertainty and imperfect knowledge. This uncertainty can be modelled as interval model. An approach composing three steps is proposed. Multi-parametric programming is used to calculate the family of an optimal solution. Two examples are proposed to illustrate this approach.

The majority of software quality cost models is by design capable of describing costs retrospectively but relies on defect estimation in order to provide a cost forecast. We identify two major approaches to defect estimation and evaluate them in a large scale industrial software development project with special focus on applicability in quality cost models. Our studies show that neither static models based on code metrics nor dynamic software reliability growth models are suitable for an industrial application.

Using a value creation perspective we analyse firms¿ strategies in footwear industry in Alicante (Spain). Production offshoring has been the key to enabling successful firms to survive in a sector that social agents have for decades perceived as permanently in crisis. In a period of great changes, local firms have not only fought to survive by maintaining activities with a high added value in the region but have also in some cases based their strategies on maintaining production activities in the same region in order to generate a high value for rapid response to the European Union regional market.

Industries such as telecommunication, cellular phone services or online content providers supply varieties of services to their customers for a specific subscription fee for a given duration of time. Controlling churn rate is an intricate operation for such industries because of the multiplicity of customers, diversity of services and various usage patterns. It may be recorded, in its simplest form, for each customer whether she/he uses different types of services during each data gathering period. Hence, usage behavior of an individual customer could be represented by a binary vector, which may be statistically modeled as a multivariate discrete distribution. This paper presents how to employ control charts for multivariate attribute characteristics to monitor systematically the mean of the customers¿ usage pattern along the time. It is shown that applying the appropriate method allows the firm to detect quickly significant changes in usage behavior and so prevent from customer churn by remedial marketing policies.

Acceptance control charts are one of the effective tools for monitoring capable processes, where the fraction of produced non-conforming items is very low. Due to high capability of the process, in these charts, controlled changes in the process mean are allowed. Although acceptance control charts are widely used in practice, it is often designed without considering the economic aspects that would result in economic drawbacks from the process and cause in increasing process costs. In this paper to make the acceptance control charts more applicable, an economic model is presented. In this model, control chart parameters, sample size, sampling interval, and the control limits coefficient are determined such that the expected cost of the process is minimized.

The mixed-Weibull distribution is widely used to analyze the burn-in time. Kececioglu had presented its parameter estimation method with application of Weibull probability plot (WPP) such a graphic analysis method. However his method is not easy to estimate parameters when the data loses the failure mode information. A self-organizing map neural network (SOM) is used to cluster the classification of failure mode. We combined SOM with Kececioglu¿s method to estimate the parameters of mixed-Weibull distribution. Some simulation studies are given to present the accuracy of parameter estimation of our method under small sample size.

This paper rather focuses on analyzing the impact of different network tie strengths on exploratory and exploitative innovation success. The case of Haitian Group is employed to explore and explain the relative propositions. Our key claim is that the benefits of each type of firm tie not only vary across each other but will be moderated by market uncertainty such that certain types of ties will matter more or less under certain conditions. Specially, strong ties are valuable in environments that require exploitation, while weak ties would be more appropriate for exploration. From the firm as a whole, exploration and exploitation are two essential innovative models, under which firms need make a reasonable choice between them according the development stage, market environment and innovative targets, and maintain the number of strong or weak ties at a reasonable proportion.
