Title: LEK 421 Production Economics


1
LEK 421 Production Economics
  • Activity Analysis first steps into Application
  • Rae, (1994). Chapter 2, pp. 11 - 28

2
In general
  • Analytical and processing capabilities of
    computer software is utilised
  • Typical spreadsheet packages (MS Excel, Lotus,
    etc.)
  • Electronically connected and cross-referenced
    TABLES containing DATA and FORMULAS
  • Too much CLUTTER reduces usefulness

3
Typical input output data sheet
4
Organizing data sheets
  • Use of LOGICAL sheet distinctions and NAMES
  • COEFFICIENTS (Table 2.2, p.16) records input
    output flows per activity per time period (e.g.
    seed requirement for pumpkins, tomatoes and
    onions, respectively, per quarter) NOTE how the
    sheet is setup
  • ACTIVITIES (Table 2.3, p.19)
  • PRICES (Table 2.4, p.21)
  • INCOME COST MARGINS (Table 2.5, p.24)

Algebraic notation
  • Activity number j for j 1, , J
  • Amount of input i (for i 1, , K) used
    by activity j in time
    period t (for t 1, ,
    T)
  • Output n (for n 1, , N) from activity
    j in period t
  • Cost of the ith flow input into activity j
    in period t
  • Unit price of the nth output of activity j
    in period

8
Algebraic notation
  • Total cost of flow inputs
    and variations thereof
  • (what is the difference between equations 2.1
    2.1 and 2.1?)
  • Activity Revenues
  • (what is the meaning / reasoning behind the
    summation signs, i.e. what is assumed variable?)
  • Activity gross-margins
  • Total Gross-Margin
  • Demand for fund inputs
  • Feasibility requires
