Nowadays, customer demand for order variety, short-lead time, and fast delivery has created a great impact on manufacturing problems such as production scheduling, job sequencing, vehicle routing, binpacking, and loading. Addressing the related problems of machine scheduling is even more crucial than ever. For many years, most scheduling research has focused on problems with deterministic parameters. In real-life applications, many systems exhibit dynamic behavior characterized by a set of dynamic parameters. This fact is commonly recognized in control theory, systems engineering, and many other areas. Scheduling with time-dependent processing times is one of these important models. Research on time-dependent problems has spawned a new area in the scheduling field. It has uncovered many new properties that are absent in classical scheduling theory and led to new methodological approaches to algorithm design and NP-complete reduction. Due to their theoretical challenges and practical values, scheduling with time-dependent processing times has attracted a considerable amount of research attention in the literature.

This special issue is devoted to publishing original and significant results on “scheduling with time-dependent processing times” This special issue will cover a wide range of topics covering new theory development, innovative modelling and analysis, fundamental methodological breakthroughs, and novel applications. Papers can be theoretical, methodological, computational, or applicationoriented. Potential topics include, but are not limited to:

• Scheduling with learning effects
• Scheduling with aging effects
• New models for scheduling with time-dependent processing times
• New methods for dealing with scheduling with time-dependent processing times
