Milk-run logistics (MRL) allows the multiple enterprises in an industrial park to integrate their small-batch materials handling tasks into a highly shared logistics process to avoid redundant logistics consumption. Yet the performances of such collaborated process are often affected by the unexpected operational dynamics factors of MRL process, e.g. suppliers' unstable production rates. This paper, firstly, discusses how to apply system dynamics (SD) approach to design the structure and parameters of the MRL system so as to achieve a statistical optimization with operational dynamics. Then, the MRL system is further simulated by SD in RFID-based information sharing environment, to investigate the comparative advantages of typical RFID application schemes. RFID benefits and the corresponding RoI-based economic analysis are both conducted to provide a comprehensive instruction for those MRL managers.

This paper is part two of a preliminary study on design and development of a journal focused crawler system using EBD methodology. In this paper, the authors continue to apply EBD on the case study. Based on the result of the environment analysis, the authors took the step of conflict identification. Through conflict identification, the authors found that the critical conflict of design and development of a journal focused web crawler system is “to identify the parsing rule to download maximum content within minimum time”. This critical conflict is also the root conflict, so later on by generating primitive solution to this critical conflict, the authors successfully solve the design task and reach its original design goal. Finally, through this case study by applying EBD, it displays that EBD can help designer find the critical conflict and generating the corresponding solutions.

Sustainability has become a crucial element for the world to generate profit while keeping its citizens to live in a healthy environment. As a key contributor of our society, manufacturing industry not only generates the most profit and employment, but also contributes a lot of violence against human rights and environment. This paper has combined sustainable manufacturing with Six Sigma, which is the most useful tool for continuous improvement, to create a systematical framework for manufacturing practitioners to achieve sustainable manufacturing. This framework has given detailed steps from problem definition to achieving leadership in sustainability in order to maintain the efforts. It also allows engineers to easily adjust this framework based on the specific organizations' situation.

The importance of innovation in the world's economy, now undeniable, draws great attention to the need to improve organizations' creative potential. In the last 60 years, hundreds of books have been written on the subject and hundreds of webpages display information on how to be more creative and achieve innovation. Several North American and European universities offer graduated programs in creativity. However, building an effective and validated creativity training program is not without challenges. Because of the nature of their work, engineers are often asked to be innovative. Without aiming for a degree in creativity, could future engineers benefit from training programs in creativity? This article presents the conceptual framework and pedagogical elements of a new course in creativity for engineering students.

It is in a high demand to automatically monitor and diagnose tool wear, tool fault, or tool damage during machining process to increase efficiency and product quality and reduce production cost. This paper investigates an online tool condition monitoring method using acoustic emission signal in milling operation. The flank wear (VB) is investigated as the system fault. The nature of faulty signals in tool condition monitoring (TCM) is time varying. Therefore time-frequency transformation is an ideal analysis tool for signal interpretation. Short-time Fourier transform (STFT), Wavelet transform, S-transform, the smoothed pseudo-Wigner-Ville distribution and the Choi-Williams distribution are used for signal decomposition and two-dimensional (2D) principal component analysis (PCA) is implemented for dimensionality reduction. A 2D correlation analysis represents the deviation of the faulty signals from the healthy signal and a curve fitting approach is used to find the tool fault. Experimental tests are used for validation and the efficiency of each time-frequency transformation method in the designed TCM system is evaluated and compared.

The distributed detection methods for mechanical structural damage have been researched in these years, but there are some key problems existing in operations such as complex calculation, a lot of testing points. Aiming at the existing shortcomings of the distributed mechanical structural damage detection, this paper puts forward a new method by using distributed Fiber Bragg grating (FBG) sensors combining an interpolation algorithm, and predicts damage region through the limited testing points to avoid the deficiency caused by a large number of detection points. On this basis, taking the thin steel plate with four fixed comers as the object of study, the experiment system is set up using some FBG sensors, and its results verify the feasibility of the method with the interpolation algorithm.

Flutes, as the major geometric part of the solid end-mills, cannot be ignored while evaluating the tool's stiffness. In this work, the free-form profile of flute shape is obtained based on the CAD/CAM simulation of end-mills and the corresponding inertia is calculated through discretizing the cross-section into a group of finite rectangular elements. The inertias with various flute shapes are calculated using the discretizing method. Based on the statistical analysis of various flute shapes, a power equation in terms of tool radius and core radius is proposed to calculate the inertia. This work provides an efficient solution of calculating the inertia of solid end-mill flute, which could contribute to predicting the static and dynamic behaviours of solid end-mills.

The ability to develop new products to compete in existing or new markets is a core competency of many successful companies. Companies can assess their success from different perspectives, including the overall innovation strategy at company level. This paper evaluates 56 success metrics through the course of product lifecycle (PLC), by considering the influence of the company's business innovation strategy. Data is collected by using survey questionnaires with experienced product development managers of 21 Canadian and Danish companies, mainly practicing in mechatronics and aerospace industry. Outcomes show no statistically significant difference among innovation strategy attributes. `Financial' and `market share' are the most important success indicators in early PLC with `product' and `process management performance' being more important in the late phase. Moreover, sets of success metrics are proposed during course of the PLC. These aim to guide companies in determining critical success factors and set ideal practices in measuring the success of their products.

An experimental study is conducted to research the passivation effects of cutters on cutting forces, tool life, and size effect in milling of Inconel 718. Cutting forces and tool life of passivated cutters with different cutting edge radiuses are measured and compared in plunge milling. The results show that, with the increase of the cutting edge radius, cutting forces keep increasing while tool life increases first and then decreases. When the cutting edge radius is 7.9 μm the tool life of passivated cutter reaches its maximum under experimental conditions. The unit cutting force per cutting area on the tool edge is adopted to evaluate the size effect of passivated cutters in end milling. The results show the effect size of tool edge is obvious when the cutting depth is less than the cutting edge radius. This effect is more significant with the decrease of the cutting depth.

Thermally induced errors have been significant factors affecting machine tool accuracy. In this paper, a novel deformation measurement method of machine tools based on optical fiber Bragg grating sensors for thermal error compensation has been illustrated, a deformation measurement system has been implemented. Strain data is gauged by multiple FBG sensors glued on the specified locations of the machine tool, and then transformed to deformation. Moreover, the displacement of the machine tool spindle is also gauged for evaluation.
