Reasons for simulation being underutilized • Simulation modeling is a time-consuming and knowledge/information intense process • Most models developed are customized “rigid” models that cannot be reused or easily adapted to other even similar problems (Arons 1999, 2000; Zhou 2004) • Conceptual modeling is a critical step that directly affects the quality and efficiency of simulation projects, but hardly supported with current technology, and still a very difficult and ad-hoc process that depends on the skill and experience of individual modelers (Mclean, 2001; Robinson, 2004)
On Sunday, March 30 a fight occurred in the Club Room, the employees’ cafeteria of Mid-States Community Services’ Housing Department, between a housing administrator-intern and a building technician. The two men grappled for several seconds, rolling on the floor and throwing punches, until they were pulled apart by two interns and another technician who were standing by when the fight broke out. Aside from a bloody nose and a puffed left eye, the intern who had been
