Seru production system, which can achieve flexibility and efficiency at the same time, is a new form of production organization developed in Japan, and seru is regarded as an ideal production mode for realizing mass customization. However, theoretical research for seru production is not sufficient enough to guide the production practice. In this paper, we will consider a seru loading problem with worker-operation assignment in a single period. A mathematical model is proposed dedicated for the problem, and then, a heuristic algorithm is designed to solve the proposed model. Finally, the practicality and effectiveness of the model and algorithm are verified by a numerical example.

Setting an optimal inspection plan for fatigue critical offshore piping relies on accurately estimating its remnant fatigue life (RFL). Several modeling approaches, such as knowledge-based, model-based, data-driven, fusion techniques etc., have been used to build RFL models in the past. The aim of this paper is to review these approaches and thereby recommend the most favorable approach for building a probabilistic RFL model for offshore piping. Firstly, a brief discussion about the aforementioned approaches is presented. Thereafter, a comparison is made between these approaches. For instance, there is uncertainty in model-based approaches, due to the assumptions of the underlying physical model, which poses substantial limitations on this approach. Conversely, a data-driven approach exploits the monitored operational data associated with the condition of the piping system. Fusion technique combines the features of the former two approaches and is recommended to build a model for estimating the RFL of offshore piping.

User-driven Customization (UDC) is a promising concept to react on current developments in the markets. However, until now no successful applications of UDC for technical products exist. Therefore, this paper develops and implements a continuous toolchain for UDC from the customization toolkit via an OI-platform to the production back-end. The resulting prototype achieves the proof of concept for the feasibility of UDC: Components customized by users are directly transferred to a flexible production system and are manufactured there. To achieve this the paper builds on existing concepts as well as studies and derives a toolchain concept. It is adapted and implemented to realize a successful prototype.

This case study arises from the need to make more robust and effective quality assurance procedures of the products by automating the final inspection process. The case study explains how the automation of the inspection process was performed in a company from the automotive sector. Knowledge, involvement and commitment of operators and respective managers should not be neglected because their reaction against the change procedures influence the success of any automation performed. The successful introduction of automation contributed to a more efficient process and from the pilot station to the remaining stations problem solving and continuous improvement was evidenced.

Building environment plays an important role in ensuring a healthy and productive environment for indoor occupants. However, with the increasing demand for comfortable thermal environment and the call for sustainable building operation, achieving a balance between energy consumption and user's thermal preference is challenging. From the informatics perspective, previous studies mainly focused on intelligent building system and occupants activity analysis, while the research on knowledge discovery from building information for optimized building operation is less emphasized. In this paper, we propose a framework for information processing and knowledge discovery for sustainable building environment. Using ubiquitous wireless sensor networks, we showcase how we can feasibly collect and analyze sensory data for the benefit of building environmental assessment and building system control. A case study involving indoor environmental monitoring at two university offices is presented to showcase our approach. We then conclude our work with some discussion on future works.

This paper presents a hybrid Simulation based Optimization (SbO) approach to solve job shop scheduling problems. SbO structure for classical job shop scheduling introduced by [6] is extended for flexible job shop scheduling problem (FJSSP). Performance of SbO is bench-marked in terms of number of decision variables, constraints, objective value and computational time against various Mixed Integer Programming (MIP) based methods from literature. SbO outperforms for all the parameters and performs better with increasing problem size. Further, an hybrid solution architecture, Combined Simulation & Optimization (CSO) is introduced which integrates SbO and MIP to expedite the convergence to exact optimal solution. Results for CSO are also bench-marked against MIP based approaches, which shows that CSO performs better and converges faster.

This paper presents a study of frequency effects on the heating induction process for aluminum alloys. Our objectives are to deal with the more general induction heating issues in the semi-solid metal forming by taking into account the conditions of radiation and convection during the heating combined with cooling process at the surface of samples, hence the spatial-temporal variation of temperature on the whole sample volume. The Lab experiment for a cylinder aluminum alloy and numerical approaches for the physical model of a 2D heat transfer equation with the boundary conditions of convection and radiation were carried on. It is interesting to find that with a smaller rank of heating frequency 21-24KHz on the aluminum alloy, the distribution of the temperature is very homogenous on all samples from the center to surface areas, i.e. on the whole heated volume. We also observed that the quality of our samples after the induction heating process was very good and the `foot elephant' pattern did not happen.

Products sold with lifetime warranties are well liked by the customer as this type of warranties secure a prolonged reliable operational or useful life, and act as a shield for the customer against inferior quality as well as the potential high repair costs during indefinite life of consumable product. Under such policies, the customer are exposed to risks of costs and product reliability as products usefullife are unsure and are not recorded well in fair trade legislations. This article proposes mathematical models to determine the customer's risk evaluation for lifetime warranty by taking into account the unsure useful life of product. Risk evaluation models are proposed to estimate the optimal warranty cost through the customer's utility function for repair costs. The sensitivity of the warranty costs are discussed graphically with respect to the customer's risk choice, customer's expected failure rate, and the customer's repair costs (in the case of customer's denial of such warranty).

This paper attempts to provide a conceptual framework on factors that affect the purchasing performance of Engineering, Procurement and Construction (EPC) companies'. Till date purchasing performance models have been published for manufacturing firms, this study fills the gap by investigating the factors that constitute Purchasing Performance of an EPC. To accomplish present research objective, an exploratory study is performed with 16 Industry experts from various EPC companies across India, Australia, USA and UAE. The findings will help in developing a purchasing performance Matrix for EPCs which can be implemented to evaluate buyer's purchasing performance at an individual level as well as departmental level. A global perspective on the construct of purchasing performance is important to understand emerging themes and new concepts that constitute the construct of Purchasing Performance for EPCs.
