Today, companies dedicated to the design and manufacture of products seek to improve processes and procedures to provide better services. In addition to this, the development of products designed to meet specific needs plays an important role when feedback is obtained, in terms of design and functionality, from the end user for the consolidation of a product. Looking for such consolidation and identifying improvement opportunities, in the present paper a redesign was made based on specific criteria to align manufacturing to mass production. The theoretical framework is established taking the bases of Concurrent Engineering (CE) and Lean Manufacturing (LM), which allows to base the redesign of a scissor wagon (case study). The proposed design was structured under the approaches of cost reduction, quality improvement and characterization of geometry to reduce weight, allowed to define an architecture capable of being aligned to a mass production. The complete procedure to perform the redesign of the wagon and the analysis criteria used to conform such architecture are reported. Finally, the strategies defined for the inclusion of the new product to production and the geometry optimization results obtained by finite element analysis (FEA) are presented.

In the garment industry, upgrading from mass production to mass customization is imperative, due to ever-changing fashion trends and customers’ increasing personal demands. Based on pattern variations, several practical mass customization methods in terms of custom-fit and co-design are developed in this study for cutting-related processes (i.e. the sizing process and the cutting process). The increment of size number by generating additional sizes and the expansion of size capacity by setting multi-sized darts are two custom-fit methods, while material (fabric) variation by spreading “rainbow plies” and module variation by making a stepwise cutting are two co-design methods. Compared with existing mass customization methods mainly related to the garment design processes, the proposed methods emphasize the garment manufacturing processes in order to resolve the conflict between personalization and cost. A case study on the women’s basic straight skirt is conducted for the performance evaluation (about personalization and cost) of the proposed methods. The experimental results demonstrate the ability of these methods to significantly raise the personalization level with an acceptable price in garment customization. This study provides a reference for garment manufacturers to make proper production strategies, enabling garment mass customization.

Each enterprise that concentrates on boosting its position on a market tries to optimize mechanisms of its activity. It can be realized mainly by development in such directions as extending shares on the market, cost reduction, introducing more effective methods of production and risk management. Increasing the level of customers’ satisfaction is reached by use of FMEA (Failure Mode and Effect Analysis) as a tool of continuous development of products and processes realized by conducting their cyclic analyses. Their results build a foundation for introducing new solutions as corrective actions that eliminate causes of defects and at the same time lead to process and product improvement.The advantages of FMEA have resulted in its implementation into nearly every branch of a modern industry, both for unitary and mass production. An example of application of FMEA in mass production is a production process of beverage cans. This process is multistage, extraordinarily precise, technologically complicated and burdened by a great amount of factors that hypothetically can cause defects.The application of proper preventive actions aimed at defining both potential and factual causes of defects is an essential element of increasing the effectiveness a of production line with the simultaneous production cost reduction and boosting the level of customer satisfaction.In the article, the use of FMEA in mass production on the basis of a beverage can manufacturing has been analysed. On its basis, the potential causes of defects have been isolated and eliminated.

Abstract Flexible pipes are compounded by many concentric layers, with different structural and operational functions. These layers are usually made of distinct materials, including metal and plastic. To accurately meet the working requirements of the pipes and reduce its production cost, the primary purpose of this paper is to present the cross-sectional design procedure and the case study for a specific unbonded flexible pipe is also illustrated. In this paper, the mathematical analysis and finite element analysis are employed to study the properties of pipe under different working conditions. A theoretical model for stresses and deformations of the pipe have been studied, and the obtained results have been compared with the ones from the FEM which is used to simulate the pipe under different working conditions. Additionally, the several models will be developed to study mechanical responses of pipes subjected to several loads. The results and FEA models can be useful for the designing structure of flexible pipes.

Environment Protection

The manufacturers of pulps must answer to the following three necessary requirements: • environment protection • pulp quality • production cost reduction If up to the present time, the environmental constraints have been emphasized (e.g. dioxin in late 1980's) over the two other criteria, namely quality and cost, today the challenge for the next years will be to improve each of these factors without weakening the other two. The purpose of this paper is to discuss the respective merits of the various pulp manufacturing processes with the criteria expressed above and to draw the research and development efforts to undertake in this situation. Some personal opinions will be given on the issues.

The erosion of limestone and calcarenite ridges that existed parallel to the Mediterranean shoreline forms the calcareous sand (CS) formation at the surface layer of Egypt's northern coast. The CS is often combined with broken shells which are considered geotechnically problematic due to their possible crushability and relatively high compressibility. In this research, CS samples collected from a site along the northern coast of Egypt are studied to better understand its behavior under normal and shear stresses. Reconstituted CS specimens with different ratios of broken shells (BS) are also investigated to study the effect of BS ratios on the soil mixture strength behavior. The strength is evaluated using laboratory direct-shear and one-dimensional compression tests (oedometer test). The CS specimens are not exposed to significant crushability even under relatively high-stress levels. In addition, a 3D finite element analysis (FEA) is presented in this paper to study the degradation offshore pile capacity in CS having different percentages of BS. The stress–strain results using oedometer tests are compared with a numerical model, and it gave identical matching for most cases. The effects of pile diameter and embedment depth parameters are then studied for the case study on the northern coast. Three different mixing ratios of CS and BS have been used, CS + 10% BS, CS + 30% BS, and CS + 50% BS, which resulted in a decrease of the ultimate vertical compression pile load capacity by 8.8%, 15%, and 16%, respectively.

There are few studies that have found an adequate means of assessing firms based on their specific needs for a concurrent engineering (CE) approach. Managers interested in introducing CE have little choice but to rely on their past experiences of introducing change. Using data gleaned from a nine month case study, a British-wide survey and a series of in-depth interviews, this paper summarizes the findings of a research study that examines how firms orientate themselves towards change and how they go about introducing CE to their operations. The data show that there are many benefits to introducing CE and that firms differ with respect to their needs for the CE approach. A tentative means to assess CE ‘needs’ is proposed which is based on the level of complexity of goods produced by firms. The method is currently being developed and extended to provide an applications-based framework to assist firms to improve their new product development performance.
