In the globally competitive business environment, collaborative product development has become an important strategy for enterprises to reduce risks and enhance their competitiveness. The planning phase becomes more significant and complicated when utilizing external resources to determine a product solution to achieve customer satisfaction and business goals. The decision process for assessing design alternatives depends on the tradeoffs between quality, time, and cost. In this research, we propose a framework for collaborative product development and production of modular products. It aims at linking customer requirements, generating design alternatives, and then evaluating and selecting these choices to determine the optimum solution. They are considered from both design aspects and manufacturing concerns. Product strategy is discussed as the most important factor in the evaluation process. Further, a practical application of a system-on-a-chip product planning process was carried out to demonstrate the completeness and benefit of our proposed framework. 相似文献

Producing products with multiple quality characteristics is always one of the concerns for an advanced manufacturing system.
To assure product quality, finite manufacturing resources (i.e., process workstations and inspection stations) could be available
and employed. The manufacturing resource allocation problem then occurs, therefore, process planning and inspection planning
should be performed. Both of these are traditionally regarded as individual tasks and conducted separately. Actually, these
two tasks are related. Greater performance of an advanced manufacturing system can be achieved if process planning and inspection
planning can be performed concurrently to manage the limited manufacturing resources. Since the product variety in batch production
or job-shop production will be increased for satisfying the changing requirements of various customers, the specified tolerance
of each quality characteristic will vary from time to time. Except for finite manufacturing resource constraints, the manufacturing
capability, inspection capability, and tolerance specified by customer requirement are also considered for a customized manufacturing
system in this research. Then, the unit cost model is constructed to represent the overall performance of an advanced manufacturing
system by considering both internal and external costs. Process planning and inspection planning can then be concurrently
solved by practically reflecting the customer requirements. Since determining the optimal manufacturing resource allocation
plan seems to be impractical as the problem size becomes quite large, in this research, genetic algorithm is successfully
applied with the realistic unit cost embedded. The performance of genetic algorithm is measured in comparison with the enumeration
method that generates the optimal solution. The result shows that a near-optimal manufacturing resource allocation plan can
be determined efficiently for meeting the changing requirement of customers as the problem size becomes quite large. 相似文献

The evolution of quality control in automative manufacturing is exemplified by the Renault facility in Palencia, Spain, where quality improvement is part of its three-pronged Renault Commitment 2009 strategy. New standard processes and methods have been set up under the Renault Production Way (SPR), placing a strong emphasis on personnel responsibility at Renault production plants. A number of concrete measures have been taken to enthrone deep-rooted quality as the centrepiece of the Renault manufacturing system: attentive supplier management, fine-tuned operator training, responsive quality leadership at production plants, and systematic application of certain static and dynamic tests on completion of the production process. Then final vehicle quality is validated by a rigorous Alliance-wide scoring system (known as AVES, for Alliance Vehicle Evaluation Standard), examining over 500 criteria. At the same time, quality improvement actions at production plants are driven by customer feedback, input via the dealer network in real time. Operator training is an essential prerequisite, both for the implementation of standards and for any successful quality drive 相似文献

Manufacturing products with multiple quality characteristics is always one of the main concerns for an advanced manufacturing system. To assure product quality, finite automatic inspection systems should be available and employed. Inspection planning to allocate inspection stations should then be performed to manage limited inspection resources.

Except for a finite inspection resource constraint, therefore, manufacturing capability, inspection capability, and tolerance specified by customer requirement are considered concurrently in this research.

Both the internal and external costs of a multiple quality characteristic product are considered. The inspection allocation problem can then be solved to reflect customer requirements. Since determining the optimal inspection allocation plan seems to be impractical as the problem size gets larger, in this research, two decision criteria (i.e., sequence order of workstation and tolerance interval) are employed concurrently to develop a heuristic method. The performance of the heuristic method is measured in comparison with an enumeration method that generates the optimal solution. The result shows that a feasible inspection allocation plan to meet changing customer requirements can be determined efficiently. 相似文献

Rapid sheet metal manufacturing (RSMM) is a closed loop process for making sheet metal products which uses advanced computer-aided
techniques and computer-controlled machines to produce non-ferrous tooling directly or indirectly. The tooling would be suitable
for short-run production or design evaluation of sheet metal products for which prototyping cost and lead time are greatly
reduced. The key aspect of this closed-loop process is the method used to fabricate and modify the sheet metal forming tool.
Various approaches are adopted in the preparation of the tooling for onward embossing on a sheet metal. The three indirect
approaches use selective laser sintering (SLS), stereolithography (SLA), and high-speed computer numerical controlled (CNC)
milling to build the masters from computer data models. The masters are used in the vacuum casting process to generate the
non-ferrous tooling. Comparisons on quality, lead time and cost are presented. 相似文献

This paper studies the impact of a reduction in hardware complexity on the supply-chain inventory against various customer on-time delivery alternatives and manufacturing environments. Different methods of reducing hardware complexity are proposed, and their impact on total supply-chain inventory and customer serviceability quantified. An analytical inventory optimization scheme taking into account multistage supply networks, product structure, forecast accuracy, lead-time variability, and supplier reliability is used to determine optimal inventory levels in a stochastic modeling environment. The analysis is based on a business case for an IBM midrange computer family consisting of more than 200 models and upgrades with hundreds of features. We investigate different hardware complexity reduction strategies, including low-usage feature reduction, low-volume feature reduction, and feature substitution, as well as quick response and postponement mechanisms. Our computational results show that, in a fabrication-fulfillment center environment, reducing hardware complexity results in significantly higher inventory savings than in an integrated manufacturing environment. The results presented in this paper were used to reduce hardware complexity in IBM's midrange computer division. 相似文献

This paper is based on the data collected from a survey of 66 Indian textile-related organizations carried out to ascertain issues related to effects of timely fulfillment of customer demand in supply chain management (SCM) practices. Using the data collected, fuzzy set theory has been applied to reach a decision regarding effects of timely fulfillment of customer demand on an organization. Four multi-input single-output (MISO) Mamdani fuzzy inference systems have been proposed as an alternative approach to handle the various variables that are normally considered in such cases in Indian textile organizations. First three MISO systems consist of four inputs (decrease in production lead time, reduction in overall cycle time, improvement in quality, betterment in process integration), three inputs (decrease in production cost, increase in profits, increase in market share), and three inputs (decrease in internal conflicts, increase in customer satisfaction, betterment in buyer–supplier relations), respectively, and give out single output each, namely production effect, monetary effect, and relation effect, respectively. These three outputs are used as inputs to the fourth MISO system to give out single output, termed as final effect. 相似文献

In 100% inspection, measurement errors are unavoidable. Due to these errors, acceptable products are sometimes rejected (overkill) and defective products are accepted (escape). Overkill increases production costs, while escape is a source of customer dissatisfaction. This study presents a model for calculating overkill and escape rates using process and measurement system performance data. A practical example of applying the model is also presented to calculate gage reproducibility and repeatability requirements for different production settings. Industrial managers and quality engineers can utilize the results of this study to calculate escape and overkill rates of their production systems, and to assess and improve their processes. 相似文献

The intense competition and high failure rate of product introduction necessitate a deeper understanding of customer needs for product design. The conventional process of interpreting customer statements relies on imprecise information, making it highly unlikely, if not impossible, to acquire accurate need statements for the front-end process of product development. To deal with this problem, an ontology-learning customer needs representation (OCNR) system is proposed in this paper. The system uses natural language processing tools to preprocess customer statements. The customer needs ontology is then established based on the key concepts and their relations that are extracted from the customer statements. A set of need statements are then generated using the established customer needs ontology. A word property-based method is proposed to extract more nontaxonomic relations. A case study was conducted to illustrate the proposed approach. Results of this study suggest that the customer needs ontology derived from the proposed OCNR system contains more semantics than those obtained from the existing ontology learning systems, and, therefore, might be able to generate more accurate need statements. 相似文献
