Generalized Capital Investment Planning w/ Sequence-Dependent Setups Industri...Alkis Vazacopoulos
Presented in this short document is a description of what we call the “Generalized” Capital Investment Planning (GCIP) problem where conventional capital investment planning (CIP), and specifically for the “retrofit” problem, is discussed in Sahinidis and Grossmann (1989) and Liu and Sahinidis (1996). CIP is the optimization problem where it is desired to expand the capacity and/or extend the capability (conversion) of either the “expansion” of an existing unit or the “installation” of a new unit (Jackson and Grossmann, 2002).
Figure 1 shows the three types of CIP problems as defined in Vazacopoulos et. al. (2014) and Menezes (2014) with its capital cost and time scales.
Unit-Operation Nonlinear Modeling for Planning and Scheduling ApplicationsAlkis Vazacopoulos
The focus of this chapter is to detail the quantity and quality modeling aspects of production flowsheets found in all process industries. Production flowsheets are typically at a higher-level than process flowsheets given that in many cases more direct business or economic related decisions are being made such as maximizing profit and performance for the overall plant and/or for several integrated plants together with shared resources. These decisions are usually planning and scheduling related, often referred to as production control, which require a larger spatial and temporal scope compared to more myopic process flowsheets which detail the steady or unsteady-state material, energy and momentum balances of a particular process unit-operation over a relatively short time horizon. This implies that simpler but still representative mathematical models of the individual processes are necessary in order to solve the multi time-period nonlinear system using nonlinear optimizers such as successive linear programming (SLP) and sequential quadratic programming (SQP). In this chapter we describe six types of unit-operation models which can be used as fundamental building blocks or objects to formulate large production flowsheets. In addition, we articulate the differences between continuous and batch processes while also discussing several other important implementation issues regarding the use of these unit-operation models within a decision-making system. It is useful to also note that the quantity and quality modeling system described in this chapter complements the quantity and logic modeling used to describe production and inventory systems outlined in Zyngier and Kelly (2009).
Celebrate professional transitions and successes to drive and sustain impleme...Learning Forward
Celebrations are an important component for high-quality learning communities and are critical to effective change. See how a middle school principal makes celebrations a norm in her school’s learning community and brings people together during change efforts to celebrate each other’s professional learning.
