Title:	Scheduling Casting Processes of Automotive Pistons
Authors:	Hyun-Jung Kim and Jun-Ho Lee
Abstract:	This paper addresses a scheduling problem of metal casting processes required for manufacturing automotive pistons. Pistons are processed on a given set of dedicated machines, and the machines have different speeds. There are too few operators to set up all the machines at the same time, and the setup time depends only on the piston type to be processed next. Pistons of the same type can be split into any lot size because the number of units of a piston type to be produced is large enough. The objective is to minimize makespan. This scheduling problem can be considered to be uniform parallel machine scheduling with job splitting, setup resources, and dedicated machines. We propose efficient heuristic algorithms for the problem and show experimentally that the performance of the algorithms is good enough to be used in practice by comparing it with a lower bound. We finally provide a case study.

Title:	The Influence of Absorptive Capacity on Digital Process Innovation in Manufacturing Firms
Authors:	Raphael Rettig and Tessa C. Flatten
Abstract:	Due to the fourth industrial revolution, manufacturing companies face the biggest disruption of their production processes since the rise of advanced manufacturing technologies in the last century. Therefore, process innovation will become a critical task to master in the future for many manufacturing firms around the world. The general ability of organizations to acquire, assimilate, transform, and exploit external knowledge, known as Absorptive Capacity (ACAP), was proven to positively influence product innovation and is already conceptually associated with process innovation. We are based on a sample of 729 firms from seven leading and emerging countries. The statistical analysis reveals the positive influence of potential and realized ACAP on successful digital process innovation in existing production systems, which was not operationalized so far. Additionally, we provide empirical evidence for the effect of digital infrastructure on ACAP. All in all, our findings contribute to the dynamic capability and process innovation research streams applying an established measure of Absorptive Capacity in a broad international context focusing on digital process innovation. In addition, the presented research sheds light on the importance of ACAP as a fundamental prerequisite for Digital Manufacturing technology implementation.
