Small-scale dairy farming in Bangladesh is constrained mostly due to acute shortage, high price and seasonal fluctuation of energy and protein supplements. Poor economic conditions of dairy farmers do not allow them to purchase adequate conventional energy and protein supplements. Locally available non-conventional energy and protein sources can be used as alternatives, cheaper than conventiona...

Abstract This chapter offers examples illustrating how the ‘Solver’ feature of Excel can be used to solve simultaneous equations and unconstrained constrained optimization models. other features any or simulation models introduced in this book.

We devise a simple yet highly effective technique for solving general optimal control problems in Excel spreadsheets. The technique exploits Excel’s native nonlinear programming (NLP) Solver Command, in conjunction with two calculus worksheet functions, namely, an initial value problem solver and a discrete data integrator, in a direct solution paradigm adapted to the spreadsheet. The technique...

Mechanical parameters of rock mass are essential in engineering for stability analysis, supporting design, and safety construction. The inverse analysis has been commonly used to determine the mechanical mass. In this study, a novel approach was proposed through combing high dimensional model representation (HDMR), Excel solver, numerical model. HDMR employed approximate nonlinear function betw...
