This paper shows that unemployment insurance benefits could decrease the expected duration of unemployment induced by search. An unemployed person who has to fin ance search from limited resources may use the benefits to intensify search effort and lower the expected duration of employment....

A dispatching problem with random availability of vehicles and options to send rented vehicles is considered. We assume passenger arrivals to be described by a pure-birth process. Such a problem is analytically attractive and is shown to have practical applications in vehicle dispatching models....

This paper considers a vehicle dispatching problem with competition. For Poisson arrival processes, three dispatching policies are considered, (i) a C-policy, consisting in sending a vehicle as soon as it is filled to capacity C, (ii) a T-policy, assuming an infinite capacity and consisting in...

A production system is subject to random failure. The system continuously accumulates damage through a "wear" process and the failure time depends on the accumulated damage in the system. Upon failure the system is replaced by a new identical one and the replacement cycles are repeated. A cost...
