Having RMs available is only one aspect, obtaining them is another. There are real difficulties in distribution of RMs through different Customs and Quarantine systems. These obstructions in movement of RMs are not only in the developing world, but also in aU global areas. Materials that cross international borders must be accompanied by a (or maybe 20 ) customs document. One of the key pieces of information on that document is correct allocation of the tariff number to the product. The customs tariff number directly impacts on the resolution of such matters as, most importantly, the rate of import tax and the speed through customs. Unfortunately at present there is no specific tariff number for RMs. For most producers, tariff niunber 382200000 seems to fit the biU. As discussed in Chapter 7, this issue will need to be resolved at International levels before easy movement and distribution of RMs can occur. 

The most relevant contribution for global discrete time models is the State Task Network representation proposed by Kondili et al. [7] and Shah et al. [8] (see also [9]). The model involves 0-1 variables for allocating tasks to processing units at the beginning of the postulated time intervals. Most important equations comprise mass balances over the states, constraints on batch sizes and resource constraints. The STN model covers all the features that are included at the column on discrete time in Table 8.1. 

In the same way as in the previous STN-based continuous-time formulation, a set of global time points N is predefined where the first time point takes place at the beginning T1 = 0 whereas the last at the end of the time horizon of interest Tn = H. However, the main difference in comparison to the previous model arises in the definition of the allocation variable Winn which is equal to 1 whenever task i starts at time point n and finishes at or before time point n >n. In this way, the starting and finishing time points for a given task i are defined through only one set of binary variables. It should be noted that this definition on the one hand makes the model simpler and more compact, but on the other hand it significantly increases the number of constraints and variables to be defined.

Economics is about the allocation of resources to production and the distribution of the outputs that result. Economics exists as a discipline because the resources available globally, nationally, regionally or to any industry, organisation or individual are finite. At the same time, it would appear that no amount of output could ever satisfy all human wants and desires. Taken together, this means that choices about the level of resources to allocate to various sectors of the economy or to the production of specific outputs within those sectors are unavoidable. Equally, choices about distribution cannot be escaped. Thus, economics is the science of making choices. 

UNODC s Annual Reports Questionnaire. Points allocated for trend data strong increase 2 some increase 1 stable 0 some decline -1 strong decline -2. Reported drug use trends were weighted by the proportion of amphetamines users in a country expressed as a per centage of global amphetamine use. If all countries had reported some increase , the global trend line would have increased by one point each year and would have reached 113 by 200. ... 

The global interdependence with respect to pharmaceuticals provides powerful reasons for international, legal responses. Because both the risks of disease and the benefits of pharmaceuticals raise global externalities, individuals anywhere have an interest in the appropriate use and allocation of pharmaceuticals everywhere. Both the common good and enlightened self-interest preclude us from concluding that control over and access to pharmaceuticals should be considered as entirely private matters. 

Fleischmann et al. (2006) provide a global production network planning model used at BMW that extends the simpler load planning model proposed by Flenrich (2002). The model is a multi-period, multi-product model with an objective function that maximizes the pre-tax net present value of the network. It includes decisions on product-plant allocation, production volumes, material sourcing volumes by supply region, structural and product-specific investments and use of overtime capacity. A major contribution of the model is the incorporation of the time-distribution of investment expenditures typically observed in automobile production networks. While tariffs are included in the transportation costs, the model does not consider further aspects of international trade such as currencies, duty drawbacks or local content rules which play a major role in practice.
