When compared to the manufacturing industry, the advances of intelligent and seamless project management approaches lag behind in the construction industry. This is due to the complexity of the construction projects as well as various stakeholders who acquire specific interest of the project. For instance, public building construction has many sub-tasks and numerous systematised working processes such as planning, mobilisation, scheduling, procurement and controlling. The management of the processes of each phase of the project life cycle is of great importance in order to prevent project delay and cost overrun. A particular importance is required if construction robotics is involved since precise process and scheduling information as well as feedback are critical to ensure each task is completed accordingly. This paper proposes a holistic system approach, which focuses on the process-oriented management for on-site construction. To succeed, the Process Information Modelling (PIM) concept is introduced. The main goal of PIM is to integrate Building Information Modelling (BIM) for extensible solutions with a process-based database platform, which allows for smooth data transfer and supports continuous data sharing among all stakeholders. The overall aim is to develop a collaborative way of planning, designing, producing, assembling and managing the entire project life cycle strategy. Digital documentation, simulation and real-time data are produced progressively to facilitate decision-making. A case study applying the PIM concept for the façade painting task by a painting robot for an on-going consultancy project commissioned by the construction industry council (CIC) in Hong Kong is presented. This paper is the revised version of the paper that has been published in the proceedings of the Creative Construction Conference 2018 (Pan et al., 2018).

Environmentally Conscious Design

This paper describes the outline of “life cycle design” course the author teaches and illustrates some experiences and findings with results of questionnaires to attendees of the lecture. “Life cycle design” is a half-year course to third-year students at Tokyo Metropolitan University, Japan. The main subject is environmentally conscious design focusing on life cycle thinking. This course intends to establish general and correct viewpoints toward relationship between manufacturing industry and the environmental issues, which are indispensable knowledge as mechanical engineers, rather than to educate environmental specialists. Results of questionnaires indicate that this course succeeded in increasing students’ interest in this area and awareness of importance of the environmental issues. However, some students feel bewildered because of wide variety of topics and, therefore, lack of a central theory.

Quality Evaluation System

Dynamic Alliance is becoming more and more important in manufacturing industry. Based on previous studies, a five-stage life-cycle of Dynamic Alliance is proposed in this paper. On the basis of life-cycle, taking into account both the entire life-cycle and each stage; the quality evaluation system was built. In this paper, the methods of Delphi and Multiple Factor Analysis were used to study the factors influencing the quality level at each stage, then quantitative conclusion was drew in the end. In addition, as the researches on Dynamic Alliance are still at the exploratory stage in manufacturing industry, this paper tries to provide references for further study.

The manufacturing industry must diverge from a ‘take, make and waste’ linear production paradigm towards more circular economies. Truly sustainable, circular economies are intrinsically tied to renewable resource flows, where vast quantities need to be available at a central point of consumption. Abundant, renewable carbon feedstocks are often structurally complex and recalcitrant, requiring costly pre-treatment to harness their potential fully. As such, the heat integration of supercritical water gasification and aerobic gas fermentation, unlocks the promise of renewable feedstocks such as lignin. This study models the technoeconomics and life cycle assessment for the sustainable production of the commodity chemicals, isopropanol and acetone, from gasified Kraft black liquor. The investment case is underpinned by rigorous process modelling informed by published continuous gas fermentation experimental data. Time series analyses support the price forecasts for the solvent products. Furthermore, a Monte Carlo simulation frames an uncertain boundary for the technoeconomic model. The technoeconomic analysis demonstrates that production of commodity chemicals priced at ~$1000 per ton is within reach of aerobic gas fermentation. In addition, owed to the sequestration of biogenic carbon into the solvent products, negative greenhouse gas emissions are achieved within a cradle-to-gate life cycle assessment framework. As such, the heat integrated aerobic gas fermentation platform has promise as a best-in-class technology for the production of a broad spectrum of renewable commodity chemicals.

This paper diagnoses the development of the manufacturing industry in the Seoul Metropolitan Area (SMA) using portfolio and regression analyses. Following the life-cycle perspective, four types of spatial changes of firms have been identified, namely firm formation, inflow, outflow, and dissolution, which are applied to analyze the manufacturing development in SMA. For portfolio analysis, we propose the Net Formation Index and Net Inflow Index to measure the spatial changes of firms at the city level. The two indices facilitate horizontal comparison among cities in SMA in terms of firm growth from new opening and relocation. Using spatial regression analysis, we identify significant location factors that contribute to firm change patterns. Our tests show that a high level of industrial specialization (measured by location quotient) has a dual effect. On the one hand, high level specialization attracts new or inflow firms, particularly in the light and high-tech manufacturing industries. On the other hand, it leads to an increased number of closed or outflow firms, plausibly due to increased competition among local firms. The proposed methods can be applied to diagnose industrial development in clusters of inter-connected cities and design policy tools to boost the local industry.

In our country, the common problems of the quenching machine tool in manufacturing are lack of systematic and modular. In design and manufacturing process, there is no designing platform for the whole life cycle of the machine tool. Aimed at this problem, this paper construct a intelligent designing platform for the general quenching machine tool based on the whole life cycle. The platform can control the whole life cycle of the quenching machine tool. It used NEI biological network technology on the machine tool designing CAD system module. The platform realizes the automatic discovery, negotiation and combination of the designing resources and design knowledge. The platform generates a self-organization, self-aggregation, collaborative intelligent designing environment. The platform broke the limitations of the traditional machine tool design and solved the problems lacking of a systematic modular to the quenching machine tool in manufacturing industry .
