Energy is a key issue and is closely associated with the environment. Global environmental issues must be addressed, where the energy chain from resources to end users is of vital importance. 

Our concepts of petroleum reserves and resources and their measurements are changing to reflect the uncertainty associated with these terms. Petroleum reseiwes have been largely calculated deterministically (i.e. single point estimates with the assumption of certainty). In the past decade, reseiwe and resource calculations have incorporated uncertainty into their estimates using probabilistic methodologies. One of the questions now being addressed are such as how certain arc you that the rcsciwcs you estimate arc the actual reseiwes and what is the range of uncertainty associated with that estimate New techniques arc required to address the critical question of how much petroleum we have and under what conditions it can be developed. 

The workshop was co-chaired by Dr. Luis Marin, Professor of Geology at the Universidad Nacional Autonoma de Mexico (UNAM— National Autonomous University of Mexico) and Dr. Henry Vaux, Professor of Resource Economics and Associate Vice President Emeritus of the University of California, Berkeley. The workshop addressed science-based decision making in a regional (Yucatan peninsula) and topical (sustainable ground water management) context.

Other practical engineering information which can help evaluate modifications may be obtained from individual organizations, such as the American Institute of Chemical Engineers, the American Petroleum Institute, the Institution of Chemical Engineers (England), the National Fire Protection Association, etc. Chapter 13 lists a number of such resources and the mailing addresses to obtain helpful information.

The Association of Biomolecular Resource Facilities (ABRF) has been addressing the identification and ultimate resolution of such difficulties by collaborative trials [1-7]. The purpose of the 1994 trial was to discriminate between hydrolysis and the chromatographic analysis as a possible major source of errors, and additionally to test cystine analyses as part of a continuing effort. 

The discrete-time formulation employed is conceptually the original one (Pantelides, 1994), with the necessary adjustments to consider a periodic mode of operation (Shah et al., 1993). Nevertheless, to ensure that the problem is addressed more systematically and that the model is reusable when the number of tasks, resources and chemicals is changed, other model entities are used. Processing tasks (K) are associated to a given chemical (I) and also to a system of equipment units (X), while cleaning tasks will be defined for each unit (M) and for all combinations of chemicals /, / with ii P. Two sets of binary variables identify the starting point (ieT) of these tasks Nn, and... 

The doing stage of the cycle also addresses roles and responsibilities within the system. Expansion of the management system to address sustainability may require the assignment of role and responsibilities to individuals whose activities were not primarily associated with the original system activities. These may include representatives from human resources, accounting, investor relations, or even marketing departments.
