Software
Software

SpaeSoft delivers high precision software for

  • strategic firm planning and risk assessment,

  • investment analysis,

  • forecasting,

  • classification and

  • optimization problems in

    • corporate expert systems,

    • decision support systems,

    • logistics,

    • sales management and

    • production scheduling systems.


The methodological basis
The methodological basis

  • SpaeSoft applies techniques of Artificial Intelligence (AI) combined with classical optimization methodology

  • Computationally demanding simulation tasks (e.g., lead-lag orders in forecasting systems, structural decisions concerning neural networks, etc) may be automatized using AI.


Target systems in risk assessment
Target systems in risk assessment

  • Risk assessment of the firm as a multiperiod decision system

  • Measuring the risk of individual investments

  • Forecasting performance of financial instruments and portfolio optimization

  • Classifying objects in nonoverlapping groups (e.g., quality control in industrial processes: working/failing products; banking: healthy/financially distressed firms)

    -> Possibilities to significant cost reductions through, e.g.

    improved production scheduling, management of logistics and explicit recognition of risk in investment decisions.


Multiperiod firm planning
Multiperiod firm planning

  • The financial statements, firm decisions and parameters for a planning horizon form an intertwined unity, a scenario:

where

xt = the key decisions of the firm in period (year) t (sales,

production, R & D, investments, financing, etc),

pt = all relevant parameters controlling the operating environment

of the firm (prices, costs, interest rates, exhange rates, chocks,

economic regulation, legislation, etc),

F = the vector function generating all financial statements and financial ratios according to strict accounting logic,

H = planning horizon

P/Lt=profit and loss statement for year t

BSt=balance sheet

CFt=cash flow statement

FRt=financial ratios

  • Assume that management has specified a strategy using human reasoning, high performance optimization technology or a combination of both, for example over the period 2008-2012:

  • We want to assess the risk surface pertaining to this strategy when the unknown parameters (pt) are stochastic.

  • The probability distributions are assumed to be mutually independent, multivariate dependence is recognized within the distributions, i.e. within subsets of the parameters.

  • The distributions are extracted by statistical methods combined with human reasoning.

  • With pt stochastic, the scenarios as a whole will be stochastic as well:

  • Risk assessment is carried out through Monte Carlo Analysis, a well-known and robust simulation technique.

  • A large number (M) of drawings of the uncertain ptare made from its underlying univariate/multivariate distributions

    • wages, sales prices, R & D, investment costs, raw material costs, interest rates, exchange rates, delivery times, manufacturing times, credit risk, machine failure, etc.

  • The scenarios will be approximately normally distributed by the central limit theorem under fairly general conditions.

  • The distribution of the simulated scenarios forms the estimated risk surface of the planned decisions.

A suitable financial criterion, for example, a critical minimum level on the return on investment – ROIc (or EBIT, Cash Flows, discounted Net Profit, etc) - may be used as a criterion for accepting/rejecting the strategy:

  • The quantitative risk profile can be obtained

    • for any item or all items simultaneously in the financial statements

    • over any planning horizon

  • The method is connectable to the technological/economic processes of the firm

    • R & D, investments, logistics, production processes, pricing decisions, marketing campaigns, etc.

Multiperiod firm planning: a summary

  • Input:

  • The managerial strategy based on

  • Human reasoning

  • Multiperiod optimization

  • Accounting logic:

  • Financial statements,

  • Uncertain parameters (prices, wages, interest rates, etc)

  • Monte Carlo Analysis:

  • Probability distributions

  • (statistical/judgemental)

  • Large-scale simulations

Output:

The risk profile of all key financial items


Risk and project appraisal
Risk and project appraisal

  • In this case the scenario represents the investment project.

  • xtcontains the profile of the planned investment, e.g.

    xt(i) = the number of units of investment object i acquired at time point t.

  • pt = {ct+, ct-, rt} contains all relevant parameters, e.g. ct+(i) & ct-(i) = cash inflows & outflows per unit of investment object i at time point t, {rt(j), rt(k), rt(m)} = {the interest rate, the cost of equity, the weighted cost of capital (WACC)} at time point t, etc.

  • Fis the evaluation function for the investment, in the simplest case the net present value formula (NPV).


Risk and project appraisal1
Risk and project appraisal

  • The probability of the project falling below the critical level NPVc is obtained by Monte Carlo simulation.


Monte carlo analysis
Monte Carlo Analysis

  • Some powerful results concerning the central limit theorem extend it to cases with finite variance and non-identical distributions as well as non-independent random numbers (Lindeberg [1922], Doukhan et al [1994]).

  • The method is used extensively in engineering, statistics, numerical mathematics and computational finance (e.g., Boyle, P (1977): A Monte Carlo Approach, Journal of Financial Economics, Hull J,C (2000): Options, futures and other derivatives (4th ed.)).

  • It is used scarcely in the Scandinavian accounting profession eventhough it has an obvious potential in risk assessment for financial planning and investment problems.
