Dynamic server assignment policies for assembly‐type queues with flexible servers

We seek dynamic server assignment policies in finite‐capacity queueing systems with flexible and collaborative servers, which involve an assembly and/or a disassembly operation. The objective is to maximize the steady‐state throughput. We completely characterize the optimal policy for a Markovian system with two servers, two feeder stations, and instantaneous assembly and disassembly operations. This optimal policy allocates one server per station unless one of the stations is blocked, in which case both servers work at the unblocked station. For Markovian systems with three stations and instantaneous assembly and/or disassembly operations, we consider similar policies that move a server away from his/her “primary” station only when that station is blocked or starving. We determine the optimal assignment of each server whose primary station is blocked or starving in systems with three stations and zero buffers, by formulating the problem as a Markov decision process. Using this optimal assignment, we develop heuristic policies for systems with three or more stations and positive buffers, and show by means of a numerical study that these policies provide near‐optimal throughput. Furthermore, our numerical study shows that these policies developed for assembly‐type systems also work well in tandem systems. © 2008 Wiley Periodicals, Inc. Naval Research Logistics, 2008     

The politics of international chemical weapon justice: The case of Syria, 2011–2017

There has been near-universal condemnation of the use of chemical weapons in the Syrian conflict. The international community has nevertheless struggled to make progress on holding the perpetrators to account. This article reviews developments at the international level in terms of Syrian chemical weapon justice between 2011 and 2017. It argues that there have been substantive disagreements between states on the rationale and means of justice in the Syrian case. It also argues that international initiatives have been tightly intertwined with developments in chemical disarmament and conflict resolution processes as well as the broader war. The article describes progress and challenges to chemical weapon justice in a number of distinct formal international mechanisms during the period studied. The analysis concludes by contextualizing international responses—including the U.S. tomahawk strikes against a Syrian airbase—to the Khan Shaykhun chemical attacks of April 2017.     

The interaction between local and international power in EU police reform in Bosnia and Herzegovina

ABSTRACT

This article explores the interaction between local and international power structures in EU peacebuilding. While citizens in a state only face order from one authority (the state), local actors in a peacebuilding context are subject to orders from two institutions (the domestic state and the peacebuilding mission). This article explores the nature of interactions of these two institutions and their effect on local police officers’ compliance and resistance. Specifically, it analyzes the example of the police restructuring process in Bosnia and Herzegovina. It demonstrates that the choices of local officers to comply or resist depended on whether the interactions between the EU Police Mission and the local police organization were positive and mutually supportive, or whether they were competitive and contradictory. The findings of the article contribute to the debates on the role of local power and the importance of local legitimacy in peacebuilding.
