Over the last three or four decades, there have been numerous optimization problems in Healthcare which have been approached by researchers. Hospital logistics which must be organized and structured in order to secure patient satisfaction in terms of quality, quantity, time, security and least cost, forms part of the quest for global performance.According to the literature review, the problem of operating rooms planning and scheduling involves different conflicting objectives while considering constraints on availability of rooms, patients and doctors. In this paper, we proposed the Two Phases Method (TPM), which is a general technique that is likely to solve multi-objective combinatorial optimization (MOCO) problems.As it is known, TPM has never been applied to solve operating room planning and scheduling problem. In this paper, we developed the TPM to resolve the cited issue, while focusing on optimizing both total completion time and patients’ waiting time.

The manufacturing industry is currently undergoing a profound change driven by digitalization and servitization. Consequently, so called smart services are gaining importance. These are digital services that generate benefits from product data. However, many companies are struggling with their strategic management – both in terms of strategy and structure. In our paper, we investigate the interdependencies. Furthermore, we propose a process model to derive the basic organizational structure of a smart service business within strategy development.

As they have become leading topics of meetings, events and conferences, real-world blockchain applications have turned niche literature into a vast and complex plethora of books, articles and papers. Unlike digital payments, however, real-world applications are dependent on oracles, whose roles and implications are often neglected in the literature. The presence of oracles negatively affects decentralization and trustless consensus, generating faulty thinking or overly positive expectations. This paper aims to enlighten the state of the art of real-world blockchain applications through a systematic literature review, exploiting the oracle problem as a lens of analysis. The results support the view that almost 90% of the inspected literature is biased or incomplete.
