Rostering at a Dutch Security Firm

The roster planning process at the Dutch security firm NVD was traditionally carried out by hand. A few years NVD was traditionally carried out by hand. A few years ago, because of changing labor laws in the Netherlands, this became practically impossible. We developed a decision support system which has four main modules. The first one checks given rosters for feasibility with respect to the complicated rules of the current Collective Labor Agreement. A second module generates feasible rosters. The third one evaluates each roster with respect to its cost and ergonomic criteria. Finally, the fourth module uses mathematical programming based methods to select high quality rosters. The DSS has received rave reviews from upper management, security employees as well as the planners, who have gained enormous insight into the planning process. The DSS is currently being implemented and will be operational within the near future.decision support systems;information systems;labor;applications;integer;programming;search and surveillance

A Situational Alignment Framework for PACS

This paper reports the outcomes of a study on an integrated situational alignment framework for picture archiving and communication systems (PACS) labeled as PISA. Following the design research cycle, complementary validation methods and pilot cases were used to assess the proposed framework and its operationalized survey. In this paper, the authors outline (a) the process of the framework’ development, (b) the validation process with its underlying iterative steps, (c) the outcomes of pilot cases, and (d) improvement opportunities to refine and further validate the PISA framework. Results of this study support empirical application of the framework to hospital enterprises in order to gain insights into their PACS maturity and alignment. We argue that the framework can be applied as a valuable tool for assessments, monitoring and benchmarking purposes and strategic PACS planning
