AbstractProduct variant design, as one of the key enabling technologies of mass customization, is the transfer of variant information among mating parts from the perspective of informatics. A dimension constraint network (DCN) among mating parts carries on the task of transferring variant information. What are the information transfer characteristics of dimensions in a constraint network is a fundamental issue to plan the product variant design process reasonably. We begin by showing the natural dynamics of the DCN from two aspects: structure and uncertainty. The information efficiency of the DCN was proposed based on its simple path to specify the information transfer capability of the network. Based on this, the information centrality of the dimension was developed by measuring the efficiency loss of the DCN after the removal of a dimension from the network, which describes the information transfer capability of this dimension. Further, the information centrality of a part was derived. Using a spherical valve subassembly, we calculated the information centrality of the dimensions in a constraint network. We determined that the information centrality of dimension is highly correlated to its out-degree. An approach to plan the sequence of the part variant design according to its information centrality was proposed. We calculated the uncertainties of the DCN and its cumulative uncertainties under different sequences of the part variant design. Results indicate that part variant design under the descending information centrality of the parts minimizes the uncertainty of the DCN. This suggests a new method of planning the sequence of part variant design.

Work In Process

Modular product design can facilitate the diversification of product variety at a low cost. Reconfigurable manufacturing, if planned properly, is able to deliver high productivity and quick responsiveness to market changes. Together, the two could provide an unprecedented competitive edge to a manufacturing company. The production of a family of modular products in a reconfigurable manufacturing system often requires reorganizing the manufacturing system in such a way that each configuration corresponds to one product variant in the same family. The successful implementation of this strategy lies in proper scheduling of the modular product operations and optimal selection of a configuration for producing each product variant. These two issues are closely related and have a strong impact on each other. Nevertheless, they have often been treated separately, rendering inefficient, infeasible, and conflicting decisions. As such, an integrated model is developed to address the two problems simultaneously. The objective is to minimize the sum of the manufacturing cost components that are affected by the two planning decisions. These include reconfiguration cost, machine idle cost, material handling cost, and work-in-process cost incurred in producing a batch of product variants. Due to the combinatorial nature of the problem, a genetic algorithm (GA) is proposed to provide quick and near-optimal solutions. A case study is conducted using a steering column to illustrate the application of the integrated approach. Our computational experience shows that the proposed GA substantially outperforms a popular optimization software package, LINGO, in terms of both solution quality and computing efficiency.

In the current market demand of rapid response manufacturing, the product variant design technology is one of the key technologies. Product variant design principles and methods are first described. Then, product dimension parameter is analyzed and product dimension parameter transferring structure is studied. Applying tree theory to product variant design, a dimension relation driving-tree of components and parts is constructed and the significance of driving-tree statistics and a dimension parameters transfer method are presented. The methods and processes which are applied to variant design and the sorting algorithm of relations are described in detail. A parameterized variant design module integrated with SolidWorks was developed with VC + +. All the above mentioned methods and processes are verified by taking a joint coupling product as an example.

Product Variant

To enhance the ability and reliability of product variant design, an object-oriented framework was constructed using an extensible module/product class for setting up a modular design model. A module/product in a class was identified as an object by encapsulating the involved information as properties and the transforming or interaction activities as operations. This extensible object was gradually optimized through communications with other objects and integrations of design knowledge in five domains. These include Customer, Functional, Physical, Process and Engineering, which is a new domain introduced in this paper. The programmatic framework was implemented and successfully demonstrated using some typical machine tool products.

Abstract: Islamic banking (further referred to as the Bank) faces two significant problems: excessive concentration in Murabaha financing contracts and high cost of funds. These two classic problems directly impact the development of the Bank and give rise to the stigma of a less innovative and unprofitable industry. This research aims to make a new product breakthrough that can help stakeholders overcome the two problems above. Term Deposit Waqf Linked Isthisna (TDWLI) has 4 variants: TDWLI Perpetual Principal, TDWLI Perpetual Principal + Profit Sharing, TDWLI Periodic Principal, TDWLI Periodic Principal, and + Profit Sharing. The TDWLI Periodic Principal is the variant that is most ready to be applied because, in accounting terms, it has been regulated in PSAK 112. In general, this TDWLI product will provide several advantages for banks to reduce the cost of funds (especially in the main variant of Waqf only). It will increase Isthisna financing, referring to OJK data in 2019, only 0.3% of total financing. In terms of accounting treatment, PSAK 112 must be adjusted especially if the Bank will release a Perpetual-based product variant. The main problem with perpetual-based products is the uncommon features. In perpetual, cash waqf cannot be withdrawn or, in other words, eternal. This research recommends that OJK is expected to study this product more deeply to develop healthy and innovative Islamic banking.Abstrak: Perbankan syariah (selanjutnya disebut Bank) saat ini sedang menghadapi 2 masalah besar yaitu konsentrasi berlebihan di akad pembiayaan Murabaha serta tingginya Cost of Fund. Kedua masalah klasik ini berdampak langsung kepada perkembangan Bank dan memunculkan stigma industry yang kurang inovatif dan tidak menguntungkan. Penelitian ini bertujuan untuk membuat terobosan produk baru yang dapat membantu stakeholders dalam mengatasi kedua masalah diatas. Produk Deposito Waqf Linked Isthisna (DWLI) dengan 4 varian nya baik itu DWLI Perpetual Pokok, DWLI Perpetual Pokok + Bagi Hasil, DWLI Periodic Pokok dan DWLI Periodic Pokok + Bagi Hasil. DWLI Periodic Pokok menjadi varian yang paling siap untuk diaplikasikan karena secara akuntansi sudah diatur dalam PSAK 112. Secara umum produk DWLI ini akan memberikan beberapa keuntungan bagi bank dalam rangka menurunkan cost of fund (terutama pada varian Wakaf pokok saja) serta akan menaikkan pembiayaan Isthisna yang merujuk kepada data OJK tahun 2019 hanya 0,3% dari total pembiayaan. Secara perlakuan akuntansi, PSAK 112 harus disesuaikan terutama apabila Bank akan merelaisasikan varian produk berbasis Perpetual. Permasalahan utama dari produk berbasis perpetual adalah ketidak umuman fitur dimana dalam perpetual, Wakaf uang tidak dapat ditarik atau dengan kata lain abadi. Rekomendasi dari penelitian ini adalah OJK diharapkan dapat mengkaji produk ini lebih dalam demi perkembangan perbank syariah yang sehat dan inovatif.Islamic banking (further referred to as the Bank) faces two significant problems: excessive concentration in Murabaha financing contracts and high cost of funds.

AbstractWith an increasing demand for product individualisation leading to increased product architecture complexity and -costs, modular kits are one common measure to cope with this issue. The management of such a modular kit as well as the methodical determination of a specific product variant is key to the manufacturer's success. As multiple influence factors need to be taken into account when configuring product variants, we propose a multi-dimensional geometric optimisation algorithm, allowing for prioritising varying customer demands and thereby determining the ideally balanced product variant.

PurposeProduct variant design can only be achieved after all its constituent parts have been implemented by variant design. It is necessary to plan the sequence of part variant design reasonably. The product variant design process involves a large amount of information transfer events at the dimensional level. A reasonable product variant design process needs to make full use of the information transfer characters of parts to decrease the uncertainty of product variant design process. The existing methods of researching the product variant design process mainly focus on resource constraint and activity logic. They are deficient, however, in information transfer resolution and uncertainty management. This paper aims to address these issues.Design/methodology/approachThis paper identifies the number of dimension transfer paths and the position of dimension locating within a transfer path as being the key factors affecting the information transfer role of dimension. Information transfer utility is proposed to measure the information transfer capability of dimensions and parts. Based on these, a two-stage approach of generating the sequence of part variant design based on information transfer utility is proposed.FindingsThe uncertainty of dimension constraint network is minimal during the product variant design process when parts are implemented by variant design under the sequence generated through a two-stage method based on the information transfer utilities of parts, as does the times of parameter transferring and iteration in dimension constraint network.Originality/valuePart variant design under the sequence of descending information transferring utilities can decrease the difficulty of implementing product variant design validly and also increase the efficiency. This suggests an innovative method to planning the product variant design process reasonably from the perspective of informatics.
