## Introduction

Effective, strategic, current and operational management of modern logistics systems requires continuous monitoring and forecasting of their condition in many parameters. Especially these questions are critical in justifying the need for modernization or technical re-equipment of the logistics (supply) chains, when the issue for the evaluation of its technical and economic potential is relevant.

It can be concluded that there is the need to study the issues of formation of scientifically based logistics solutions. Moreover, by analogy with the systems theory in engineering, it comes to research of the effectiveness of these decisions in conditions of limited, incomplete and often inaccurate information. In general, the management of the logistics process is based on the adopted corporate policies and involves the coordination of related solutions in various areas (scientific, technical, economic, marketing, sales, etc.). The difficulty of solving this problem is the complexity of combining all these elements to achieve the long-run objective that is to optimize the logistics process in view of the strategic objectives of the organization.

A decision on the need to modernize the logistics system must be taken in a timely manner and formed with prior, current and forecast information based on adaptability concept with predominant use of «efficiency-cost» criterion. Adaptability means the implement of the conversion process of all currently available useful information to make effective solutions and ensure the functioning of a competitive logistics system.

The review and analysis of the methodological problems of the choice and decision-making theory in the management of the logistics process have identified the need to take into consideration the level of uncertainty. The development of these issues should be carried out on the basis of information and statistical methods and models of decision-making, taking into account the uncertainty and risks, with the construction of the adaptive forecasting models. Current advances do not allow solving these problems quite effectively. Since the methods of scientific, technical and economic analysis have specific features of their application, for example, for a multi-dimensional prediction parameter logistic systems, therefore there is a need for the information-statistical approach.

The spread of the open innovation model implies not only an increase in the internationalization of the entrepreneurial sector. Initiated by transnational companies innovations can not only overcome institutional and disciplinary barriers, but also geographical. The issues of logistic development should be addressed within the framework of the open innovations ensuring the integration of key and supporting participants of supply chains based on open innovation interaction. The level of uncertainty is influenced by the fact that the use of only open innovations in the logistic system results in fewer stochastic factors in forecasting.

The research question of this paper is to propose the methodology of investment decisions on logistics (supply) chain modernization (design) in case of uncertainty based on information and statistical technologies.

## Methodology and findings

A lot of work has been devoted to the design of logistics (supply) chain (Alonso-Ayuso et al, 2003; El Hannach et al, 2016b; Lim et al, 2017; Park et al, 2016; Pisani, 2004). Many researchers consider this problem from an economic point of view.

For example, Hämäläinen (2017) provides a literature overview on the key concepts of cost aggregation, multimodal transport, logistic chain and maritime transport.

Longo (2012) demonstrates the need to consider different sustainability aspects in supply chain redesign and optimization problems. To this end a simulation model of local pharmaceutical business retail is presented as application example. Three different sustainability aspects are considered (technical sustainability, economic sustainability and environmental sustainability) when investigating two different problems: the addition of new pharmacies to the supply chain and optimization of the supply chain routes.

Nagurney (2010) proposes a framework for supply chain network design and redesign that allows for the determination of the optimal levels of capacity and operational product flows associated with supply chain activities of manufacturing, storage, and distribution at minimal total cost and subject to the satisfaction of product demands.

Investment decisions on logistics (supply) chain modernization is generally an evaluation of the alternatives proposed for the investor based on the indicators and the selection of the projects according to the existing conditions (constraints). If possible, the multi-criteria problem usually reduces to a one-criterion issue by introducing a generalized criterion to simplify the problem (Khovanov, 2005). In our case, this criterion could be the generalized index of the investment project attractiveness.

For the convolution of partial indicators related to a particular investment project, it seems reasonable to use the method of the potential distribution of probability. An information situation exploiting this method is characterized by the fact that investors know only the data on the corresponding private characteristics of investment projects. In this case, it seems appropriate to put forward a hypothesis of a linear convolution of some partial dimensionless parameters (Khovanov, 2005; Garanin et al., 2015).

There is a sufficient number of different methods for determining the weights of such convolutions. They are all based on a particular behavior model of the social and economic systems, which is usually postulated informally. Meanwhile, a greater objectivity is typical of the models built using the principle of maximum uncertainty. One possible approach to evaluate these weights, which is based on this principle, is the method the potential distribution of probability. The content of this situation may be represented by the following scheme.

Let consider *n* investment projects which, in their purpose and contents, are competitors in terms of investing funds for logistics (supply) chain modernization. Each of these projects is associated with a set of characteristics that define its investment attractiveness.

_{ ij }as particular indicators of comparable projects. Initial data in this case are conveniently situated in a matrix

Weight of the j *-*th characteristic in the distribution of funds to achieve the desired level of investment project efficiency is generally unknown. It is required to assess the weight of each characteristic in the distribution of resources taking into account the objectively existing uncertainties.

_{ эj }- characteristics of the standard, which is considered as one of the projects.

_{ j }reflecting a pattern of environment behavior are found by maximizing the Shannon entropy (El Hannach et al., 2016a)

Constraints (3) postulate the normalization and constancy of the geometric mean. Physically, this means that the relative increase in the weight of the *j*-th characteristic is in proportion to the relative increment of the level of the same characteristic among the totality of the considered projects, and the proportionality coefficient depends on the level achieved.

1 | 2 | 3 | 4 | 5 | |

1. Net Present Value (NPV), mln. Rub. | 1 | 1.3 | 0.7 | 2.6 | 1.1 |

2. Profitability Index (PI) | 1.2 | 1.5 | 1.3 | 1.7 | 1 |

3. Internal Rate of Return (IRR), % | 15.5 | 14.2 | 17.5 | 13 | 17 |

4. Return on investment (ROI), % | 45 | 30 | 65 | 35 | 50 |

5. Payback period, years | 3 | 4 | 5 | 3 | 6 |

Importance (significance) of the characteristics

Projects characteristics | Coefficients |
---|---|

1. Net Present Value (NPV), mln. Rub. | 0.16 |

2. Profitability Index (PI) | 0.18 |

3. Internal Rate of Return (IRR), % | 0.20 |

4. Return on investment (ROI), % | 0.20 |

5. Payback period, years | 0.26 |

Analyzing the results of the calculations, we can conclude that the most attractive for the investor is project 4, because it has the highest generalized index.

### Emphasis on the subjective evaluations of the importance of project characteristics

Another conclusion that can be drawn on the basis of the initial data and the calculations is that the payback period is the defining characteristic of these projects is, and has the highest weighting factor. However, it makes sense to take into account the opinions and experience of qualified experts in the evaluation of the project characteristics importance. For this purpose, it is advisable to take into account the subjective opinion of experts in the formation of the matrix (5).

Subjective priority of characteristics

Projects characteristics | Priority | Coefficients |
---|---|---|

1. Net Present Value (NPV), mln. Rub. | 4 | 0.13 |

2. Profitability Index (PI) | 3 | 0.20 |

3. Internal Rate of Return (IRR), % | 5 | 0.07 |

4. Return on investment (ROI), % | 1 | 0.33 |

5. Payback period, years | 2 | 0.27 |

4. Return on investment (ROI), % | 0.27 |

5. Payback period, years | 0.27 |

Changing γ from no-confidence level (0%) to absolute confidence level (100%), we see the convergence of the results to the limits either for the purely objective or for the purely subjective assessment.

### Emphasis on the experts’ opinions in the evaluation of alternative investment projects

Parameters | Projects | ||||
---|---|---|---|---|---|

1 | 2 | 3 | 4 | 5 | |

Generalized assessment of investment attractiveness | 0.64 | 0.64 | 0.56 | 0.66 | 0.55 |

Thus, the most preferred investment project is project 4.

### Investigation of the effect of choice standard

We have shown above that formalizing information situation of potential distribution of probability involves the formation of Bayesian criterion (1), to assess the weights of which we introduce the dimensionless parameters r_{
ij
}. It uses the concept of a “standard”, and each of the projects can be considered as such. In fact, it is necessary to consider the following feature of this method.

Initial data for investigation

Characteristics | Projects | ||||
---|---|---|---|---|---|

1 | 2 | 3 | 4 | 5 | |

1 | 11 | 34 | 24 | 67 | 76 |

2 | 23 | 23 | 54 | 46 | 34 |

3 | 21 | 12 | 34 | 45 | 56 |

4 | 23 | 32 | 23 | 32 | 23 |

5 | 43 | 56 | 12 | 11 | 44 |

_{ ij }= x

_{ ij }/x

_{ Бj }in formula (1). The following Table 7 presents input data in case project 1 is selected as a standard (basic project).

Input data (project 1 – basic one)

Characteristics | Projects | ||||
---|---|---|---|---|---|

1 | 2 | 3 | 4 | 5 | |

1 | 1 | 3.09 | 2.18 | 6.09 | 6.90 |

2 | 1 | 1.00 | 2.34 | 2.00 | 1.47 |

3 | 1 | 0.57 | 1.61 | 2.14 | 2.66 |

4 | 1 | 1.39 | 1.00 | 1.39 | 1.00 |

5 | 1 | 1.30 | 0.27 | 0.25 | 1.02 |

The use of the expression (4) when selecting project 1 as the basic one (standard) gives the following values of weights.

\( {P}^{(1)}={\left[0.07\kern0.5em 0.17\kern0.5em 0.17\kern0.5em 0.23\kern0.5em 0.36\right]}^T \).

Similarly, the weights are calculated when selecting project 2, 3, ...: as a standard.

\( {P}^{(2)}={\left[0.17\kern0.5em 0.14\kern0.5em 0.08\kern0.5em 0.25\kern0.5em 0.36\right]}^T \);

\( {P}^{(3)}={\left[0.13\kern0.5em 0.35\kern0.5em 0.24\kern0.5em 0.20\kern0.5em 0.08\right]}^T \);

\( {P}^{(4)}={\left[0.28\kern0.5em 0.22\kern0.5em 0.23\kern0.5em 0.21\kern0.5em 0.06\right]}^T \);

\( {P}^{(5)}={\left[0.27\kern0.5em 0.14\kern0.5em 0.25\kern0.5em 0.13\kern0.5em 0.21\right]}^T \).

Analyzing the results, it must be admitted that the choice of the project as the base one affects the weighting factors of their characteristics. In other words, the weight of the private indicator in the complex characteristic of the project is highly dependent on the choice of the base object for comparison. Since the weighting factors are only for internal operations, their use for other purposes ignoring this method is incorrect. Let us consider the effect of the base project selection on a generalized indicator (1). To do this, using the above-mentioned weight P_{
j
}, we calculate the value of the indicator (1) for the different cases of base project selection:

\( {b}^{(1)}=\left[1.00\kern0.5em 1.27\kern0.5em 1.17\kern0.5em 1.56\kern0.5em 1.79\right] \);

\( {b}^{(2)}=\left[0.79\kern0.5em 1.00\kern0.5em 0.92\kern0.5em 1.22\kern0.5em 1.41\right] \);

\( {b}^{(3)}=\left[0.86\kern0.5em 1.09\kern0.5em 1.00\kern0.5em 1.33\kern0.5em 1.53\right] \);

\( {b}^{(4)}=\left[0.64\kern0.5em 0.82\kern0.5em 0.75\kern0.5em 1.00\kern0.5em 1.15\right] \);

\( {b}^{(5)}=\left[0.56\kern0.5em 0.71\kern0.5em 0.65\kern0.5em 0.87\kern0.5em 1.00\right] \).

The comparison b^{
(i)
} shows that the selection of the base project also strongly affects the absolute values of the generalized indicator. Therefore, values can be used only for comparison on a «better or worse» principle in the formation of a number of preferences for the projects under consideration. Thus, it is easy to see that, in all cases, when selecting the basic project, a number of preferences remains identical: 5, 4, 2, 3, 1, despite the fact that the absolute values vary significantly in case the basic project changes.

### Research limitations/implications

Thus, the potential distribution of probability can be successfully used for the qualitative comparison of a number of projects in the form of preferences. The quantitative evaluation of both weights and generalized indicators calculated by this method is relative and strongly depends on the choice of the base project.

The proposed approach enables the integration of previously developed procedures for statistical analysis of data, and implemented in the form of program information processing technologies with methods of decision-making support based on maximum uncertainty principle. In this case, a multi-dimensional prediction of the logistic system parameters can be represented in the form of branched algorithm, which is based on well-known methods of different types of analysis such as correlation, time series, factorial and mathematical analysis. At the same time, increase of the objectivity and validity of the results is ensured not only by the implementation of the consistency principles, but also by the introduction of a comprehensive verification of the forecast results of the procedure. Automation of this kind of algorithms allows improving decision support system and thereby contributing to the adequate and efficient management of logistics systems.
