Running-time analysis of ant colony optimization (ACO) is crucial for understanding the power of the algorithm in computation. This paper conducts a running-time analysis of ant system algorithms (AS) as a kind of ACO for traveling salesman problems (TSP). The authors model the AS algorithm as an absorbing Markov chain through jointly representing the best-so-far solutions and pheromone matrix as a discrete stochastic status per iteration. The running-time of AS can be evaluated by the expected first-hitting time (FHT), the least number of iterations needed to attain the global optimal solution on average. The authors derive upper bounds of the expected FHT of two classical AS algorithms (i.e., ant quantity system and ant-cycle system) for TSP. They further take regular-polygon TSP (RTSP) as a case study and obtain numerical results by calculating six RTSP instances. The RTSP is a special but real-world TSP where the constraint of triangle inequality is stringently imposed. The numerical results derived from the comparison of the running time of the two AS algorithms verify our theoretical findings.

Sustainability evaluation of manufacturing technologies is a vital part of decision process in sustainable manufacturing, particularly for decisions on transfer/adoption of new sustainable manufacturing innovations. This paper highlights a study on metrics-based sustainability evaluation of technologies in manufacturing, with emphasis on the technical, economical and environmental sustainability assessments. On the basis of three types of sustainability evaluation metrics proposed in this paper, our study integrates technology assessment, cost analysis and environmental evaluation to support decision-making for selection of sustainable manufacturing processes. Case studies about sol-gel coating and powder coating are explored in the paper to test the proposed sustainability evaluation methods and metrics. The assessment results provide quantitative justifications used in technology transfer of the new sol-gel coating innovations. The results also help potential technology adopters to reduce their implementation risks of the sol-gel coating process in automotive decorative applications.
