Theme IV

 

Value Optimizing, Scheduling and Control

The primary research focus in this theme is the immediate control of the flow of materials through this complex network to minimize the costs of meeting the market commitments given the availability of forests to be harvested. The main challenge at every part of this network is to optimize production and allocation decisions so that overall value is maximized. There is a constant tension between immediate local optimization and the integration, both spatially and temporally, of the control decisions that realize maximum overall value. Technology developments have made local optimization increasingly possible. GIS and cruise systems have made it possible to identify the value of certain stands given a set of harvest prices and to identify those with highest value with respect to those prices. Alternative harvest technologies are available ranging from full-tree logging to a variety of cut-to-length systems. Bucking optimization systems are available that can maximize the value from each tree given the log prices. Given unit transportation costs and mill prices, it is possible to calculate product allocations that maximize the value of products produced on a given stand. At a sawmill, given product prices and the ability to scan log dimensions, it is possible to optimize the log breakdown into various product classes. At every level of the value chain, local optimization is possible. Some of these optimization problems are easily modelled and solved, others may be more algorithmically challenging. However, the key point is that the sum of all these local short-term optimal decisions is unlikely to be even feasible for the overall problem of allocating the available immediate wood supply to meet the market commitments. In all these local problems, it is the integral of the decisions made that produces value and enables the overall system to meet the requirements of equating supply with demand.

The value chain production problem involves the classic issue of the design of control mechanisms that strike the correct balance between centralized and decentralized control. Coordination and some degree of centralization are necessary in order to achieve the maximum possible value but the system is too complex for full central control. Effective operation requires that the individual operators be given the flexibility to use their own creativity and the incentives to achieve good performance. In many cases, the industry structures itself with independent contractors and different enterprises necessitate a decentralized approach. The requirement is for information and the optimization capabilities to make such a decentralized approach produce close to the maximum achievable value.
