Livermore Industries uses a kanban system to manage production of the KR-9 subassembly. In a ten-hour day, they use 1500 units and use containers that can hold 50 units each. It takes 45 minutes to fill and move a container of parts to the right place on the KR-9 line that is currently rated at a 15% safety factor. How many production cards are needed

Four key marketing decision variables are price (p), advertising (a), transportation (t), and product quality (q). consumer demand (d) is influenced by these variables. the simplest model for describing demand in terms of these variables is: d = k – pp + aa + tt + qq where k, p, a, t, and q are constants. discuss the assumptions of this model. specifically, how does each variable affect demand? how do the variables influence each other? what limitations might this model have? how can it be improved?
