Of particular importance in practical scenarios is the need to consider collaboration of rescue units. This task has hardly been addressed in the literature. We contribute to both modeling and solving this problem by (1) conceptualizing the situation as a type of scheduling problem, (2) modeling it as a binary linear minimization problem, (3) suggesting a branch-and-price algorithm, which can serve as both an exact and heuristic solution procedure, and (4) conducting computational experiments - including a sensitivity analysis of the effects of exogenous model parameters on execution times and objective value improvements over a heuristic suggested in the literature - for different practical disaster scenarios. The results of our computational experiments show that most problem instances of practically feasible size can be solved to optimality within ten minutes. Furthermore, even when our algorithm is terminated once the first feasible solution has been found, this solution is in almost all cases competitive to the optimal solution and substantially better than the solution obtained by the best known algorithm from the literature. This performance of our branch-and-price algorithm enables rescue organizations to apply our procedure in practice, even when the time for decision making is limited to a few minutes. By addressing a very general type of scheduling problem, our approach applies to various scheduling situations.","lang":"eng"}],"publication":"European Journal of Operational Research","issue":"1"},{"language":[{"iso":"eng"}],"_id":"4517","user_id":"1112","year":"2019","title":"Digitalization of Work Systems—An Organizational Routines’ Perspective","status":"public","author":[{"full_name":"Wolf, Verena","first_name":"Verena","last_name":"Wolf","id":"23633"},{"id":"49160","full_name":"Bartelheimer, Christian","last_name":"Bartelheimer","first_name":"Christian"},{"id":"59677","full_name":"Beverungen, Daniel","first_name":"Daniel","last_name":"Beverungen"}],"conference":{"end_date":"2019-01-11","start_date":"2019-01-08","name":"52nd Hawaii International Conference on System Sciences (HICSS-52)","location":"Maui, Hawaii"},"date_updated":"2022-01-06T07:01:08Z","date_created":"2018-09-19T14:13:19Z","type":"conference","department":[{"_id":"526"}],"publication":"Proceedings of the 52nd Hawaii International Conference on System Sciences (HICSS-52)","citation":{"mla":"Wolf, Verena, et al. “Digitalization of Work Systems—An Organizational Routines’ Perspective.” <i>Proceedings of the 52nd Hawaii International Conference on System Sciences (HICSS-52)</i>, 2019.","ama":"Wolf V, Bartelheimer C, Beverungen D.

Experts are physicians and are assumed to differ in their cost of treating a small problem. We investigate the effects of this heterogeneity on the physicians’ level of fraud and on the patients’ search for second opinions. We find that introducing a fraction of more efficient low-cost physicians always increases social welfare, but in some cases only because of the raised physicians’ surplus. When the low-cost physicians’ cost advantage is small, imposing a share of low-cost physicians does not change the equilibrium fraud level. When the cost advantage is large, however, different changes in the fraud level occur depending on the share of generated low-cost physicians, the search rate and the initial level of fraud.","lang":"eng"}],"type":"report","keyword":["credence goods","treatment efficiency","heterogeneous experts","overcharging"],"department":[{"_id":"280"},{"_id":"475"}],"file":[{"date_updated":"2019-02-12T08:21:37Z","relation":"main_file","file_size":286367,"access_level":"closed","file_name":"WP118.pdf","content_type":"application/pdf","success":1,"file_id":"7631","creator":"jheinzel","date_created":"2019-02-12T08:21:37Z"}],"date_created":"2019-02-12T08:18:02Z","has_accepted_license":"1","status":"public","jel":["D82","I11","L15"],"user_id":"477","ddc":["330"],"volume":118,"publisher":"CIE Working Paper Series","_id":"7630","report_number":"2019-01","project":[{"name":"SFB 901","_id":"1"},{"_id":"2","name":"SFB 901 - Project Area A"},{"name":"SFB 901 - Subproject A3","_id":"7"}],"file_date_updated":"2019-02-12T08:21:37Z","citation":{"mla":"Heinzel, Joachim Maria Josef. <i>Credence Goods Markets with Heterogeneous Experts</i>.
