The Cost

Customer demands and global markets prompt companies to offer increasing product variety. The use of modular product structures is a possible strategy for providing the necessary external variety to the market and reducing costs by lowering internal variety within the company. Current research provides several approaches for developing modular product family structures. As modularity is a gradual property, these methods generate different product structure concepts and companies have to decide at an early stage and without detailed information which concepts to implement. Most existing modularization methods offer only little or no support for decision making, particularly in terms of cost effects. This article illustrates the cost effects of variety and modular product family structures, the various cost impacts of variety management strategies and modularization methods in a literature review. A new approach to quantify these cost effects to support concept selection during modular product family design is introduced.

The Impact

A radiological dispersion device is a weapon that combines radioactive material with conventional explosives for spreading radioactive material across an inhabited area. This study is focused on evaluating key parameters in an radiological dispersion device scenario. The calculations were performed to include two different situations: by using explosives and by simple mechanical release. Simulations were conducted with the use of the HotSpot Health Physics Codes. The results suggest the existence of significant correlations between stability classes in scenarios where they evolve with time, producing alternations between them. As long as the stability class remains constant, this latter finding offers the possibility of creating a suitable response, based on temporal evolutions. Therefore, the purpose of this study is to: estimate the size of the potentially affected population, estimate absorbed doses, and estimate the cost-effectiveness in order to help initial responses by providing time-sensitive information about the event. A methodology capable of providing useful information allows prompt decisions and initial assessments of future risks to be made efficiently. This approach can also provide a training environment for the personnel responsible for the decision-making at an early stage of the response.

Acceptance of any new approach by the organizations depends upon the users’ needs. Currently, reducing the cost and time invested in maintenance is a major challenge for the practitioners. Moreover, symmetrical and optimal maintenance is the need of the hour and it can be achieved by increasing the durability of software. Many attributes of the quality may affect the durability of the software and identification of durability attributes is a crucial task at the early stage of software development. Thus, it is a problem that contains multi-criteria within it. With the help of quantitative estimation, software durability may be assessed symmetrically and increased. In this row, the authors of this article have attempted to posit an effective technique to assess the durability of software. Based on empirical data through research, the presenters of this article suggest that fuzzy-based symmetrical method of Analytic Network Process (ANP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) would be an accurate methodology for assessing the durability of software. For determining the efficacy of this assessment, the researchers took six alternative software of a University. The results, as presented in this paper, would serve as guidelines for the practitioners who aim at achieving the preferred software durability.

Reducing Costs

Product platforms allow companies to compete in the global marketplace by facilitating product variety, by adding, removing, or substituting components and features across a product family, while reducing costs and lead times. In many cases, developing a common platform involves determining which components are in a product family, their connections, and their spatial layouts. The development of product configurations and layouts is a complex problem and involves both discrete and continuous mathematical processes. This paper presents algorithms and an implementation to address the problem of configuring products and component layouts. The algorithms will describe the processes used to generate the product configurations based on constraints on combinations and the layout of components within the products. The implementation presents software developed to present the algorithms for the configuration and layout processes.

<p>Requirement prioritization play a significant part in overcoming problems related to requirements and it use to increase customer satisfaction. Requirement prioritization is use to verify the correct functionality of product and guarantee that the software is built within the given constrains, like budget, cost, value, time and etc. Requirements prioritization reliant on the specific requirements of customer along with prediction of importance and cost of each requirements. The approaches proposed in modern days to prioritize requirements have not been widely used because of its complexity, its inconsistency and its time-consuming factor. This paper represents an analysis on obtainable prioritization techniques based on cost and benefit and drawbacks evaluation of requirements. This paper represents a new approach of requirement prioritization, which can be easily managed, implemented and used as decision-making device by decision maker for requirement prioritization. It also overcomes the drawback of existing requirement approaches. The results of newly proposed approach shows that<br />proposed model for requirement prioritization is simple and is useful for more refined critical decisions of prioritization, keeping in view the cost and benefit.</p>

Economy Of Scope

A properly designed product-system platform can reduce the cost and lead-time to design and develop a product family and thus achieve the tradeoff between economy of scope from product variety and economy of scale from platform sharing. Traditionally, product platform planning uses heuristic and manual approaches and relies on expertise and intuition. In this paper, we propose a data-driven method to draw the boundary of a platform, complementing other platform design approaches and assisting designers in the architecting process. The method generates a network of functions through relationships of their co-occurrences in prior designs of a product domain, and uses a network analysis algorithm to identify an optimal core-periphery structure. Functions identified in the network core co-occur cohesively and frequently with one another in prior designs, and thus are suggested for inclusion in the potential platform to be shared across a variety of product-systems with peripheral functions. We apply the method to identifying the platform functions for spherical rolling robots, based on patent data.

For the more effective cost management and control of product platform, on the basis of modular product family (MPF) realization process and the cost of product family, the cost estimation model of modular product family was proposed. The manufacturing and management cost of component part level, module level and product level was estimated, and summed up to the cost of product family. Finally, a case of wheeling loader product family was illustrated to demonstrate the validity of the model.
