On the representation of timing for different structures within MRP theory

Bogataj, Marija; Grubbström, Robert W. - In: International Journal of Production Economics 140 (2012) 2, pp. 749-755

MRP Theory has been developed during the last 25 years for capturing processes concerning multi-level, multi-stage production-inventory systems in a compact way. Input–output analysis has been used to describe structures, and Laplace transforms to describe the timing relations. This theory has...

Speed limit laws in America: The role of geography, mobility and ideology

Albalate, Daniel; Bel, Germà - In: Transportation Research Part A: Policy and Practice 46 (2012) 2, pp. 337-347

Speed limits had been centralized at the federal level since 1974, until decisions were devolved to the states in 1995. However, the centralization debate has reemerged in recent years. This paper conducts the first econometric analysis of the determinants of speed limit laws and State reactions...
