he Apparent Tardiness Cost (ATC) dispatching rule was initially developed to minimize tardiness in single machine scheduling problems. ATC extensions have been frequently applied in other production settings, relying heavily on blocking idle machine capacity with a single-machine outlook; this approach may not result in the best outcomes, considering that machines have different efficiencies. This ...

Nowadays, increasing number of companies incorporates the reverse logistics decisions into their supply chain design in order to cope with the enforced international and national legislation and improve the resource efficiency and public image. This paper investigates a new stochastic optimization model for designing a single-period multiproduct multi-level reverse logistics system under government ...

This paper describes the numerical study of atmospheric ice accretion on rotating geometric cross sections, circular, hexagon and square , all having fins, to select an optimum geometric cross section for use as a rotating part of a newly- proposed designed icing sensor. Computational fluid dynamics-based numerical analyses were carried out in this research work to understand and analyse the ...

Numerical study of atmospheric ice accretion on two non-rotating circular cylinders in tandem arrangement was carried out at different operating and geometric conditions. To validate the numerical model, initially the results of ice accretion on single circular cylinder were compared with the experimental data obtained from CIGELE atmospheric icing research wind tunnel (CAIRWT) [1, 2]. A good agreement ...

Management of municipal solid waste has becoming an extremely important topic for any urban authorities in recent years due to the rapidly increasing solid waste quantity and potential environmental pollution. In this paper, a bi-objective dynamic linear programming model is developed for decision making and supporting in the long-term operation of municipal solid waste management system. The proposed ...

Additive manufacturing is a rapidly evolving manufacturing technology bringing numerous and wide opportunities for the design team involved in the process by creating intricate and customized products with saving labor, time, and other expenses. Innovative AM methods and numerous practical applications in aerospace, automotive, medical, energy, and other industries have been developed and commercialized ...

Digitalization not only improves individual performance but also helps orchestrate supply chain partners to serve a bigger goal. To fully benefit from supply chain digitalization, a high level of integration across supply chain activities is required. This chapter introduces major interactions between production management decisions and the supply chain strategy, structure, and performance to explore ...

This article focuses on studying the current literature about railway operations in icing conditions, identifying icing effects on railway infrastructure, rolling stock, and operations, and summarizing the existing solutions for addressing these issues. Even though various studies have been conducted in the past on the impact of winter, climate change, and low temperatures on railway operations, not ...

The manufacturing industry is moving from mass production towards more personalized products through mass customization. In order to adapt factories should be highly flexible and rapidly able to adjust their operations.The new technologies and concepts in industry 4.0 are important in the transition from mass-to flexible and personalized manufacturing systems. One such specific tool for increased ...

This paper investigates intuitiveness in human robot interactions with focus on remote operation and assistance. The increasing number of robot applications in small volume production requires new techniques to ease the use of these sophisticated systems. A vibrotactile device was used for experiments. Vibration patterns are developed to represent a cognitive information channel for the remote ...
