Abstract
Purpose
The purpose of this paper is to establish a situation evaluation model of the robot and ball in SimuroSot5vs5 platforms and enhance the strength of the team in a SimuroSot5vs5.
Design/methodology/approach
This paper presents a mathematical model based on situation evaluations which can improve the strength of the team in SimuroSot5vs5. The situation evaluation focus on four aspects includes scores of both sides, possession of teams on ground, ball strategy, and treat. The statistical analysis of the score can verify validity and stability of current strategy in confrontation. To evaluate the situation more effectively without blindness, possession on both teams is, respectively, evaluated. Ball strategy analyzes coordinate transformation to the ball on the ground and illustrates the circumstance of both teams on the offensive position accurately in length and breadth. To know the circumstance on the field more completely and synthetically, a threat situation evaluation model is built. An effective and practical algorithm for comprehensive situation evaluation is successfully finished. The experiments prove validity and performance of the proposed situation evaluation model.
Findings
A mathematical model is designed to achieve situation evaluation, and the strategy can change in accordance with different situations on the ground.
Research limitations/implications
The system is specifically applied to SimuroSot5vs5 platform. The extensibility of the system is limited.
Practical implications
When the robot and ball is in high speed movement, a large calculated amount will slow the speed of the system.
Originality/value
The paper shows that situation evaluation in SimuroSot decision support systems will enhance the battle effectiveness of the soccer team.

Abstract
Purpose
The purpose of this paper is to examine the association between the cost of debt (COD) and auditor industry expertise using Taiwanese data. Since previous studies (Li et al., 2010) have only examined the relation between industry specialization and COD at the audit firm level in western countries, the authors further examine the association between industry specialization and COD at the individual auditor level in an Asian context.
Design/methodology/approach
The authors use the interest rate on the firm’s debt as a proxy variable for the COD (Francis, Khurana and Pereira, 2005). The authors adopt three different methods to measure industry specialization, which consist of the auditors’ market share in terms of client sales and number of clients, and client assets.
Findings
The results indicate that the clients of industry specialists at individual auditor levels have a lower COD.
Originality/value
First, the authors extend the research of Li et al. (2010) and find that the clients of individual auditor industry specialists also have a lower COD. Second, the authors also believe the evidence on the effects of industry expertise at the individual auditor level may have policy implications for regulators and public investors. Finally, in contrast to works carried out in the US market, the authors provide empirical evidence for the relation between industry specialization and COD in an Asian market.

Abstract
Purpose
On one side, the purpose of this paper is to numerically analyze the emergency order allocation mechanism and help managers to understand the relationship between the emergency coefficient, uncertainty and emergency cost in two‐echelon logistics service supply chain. On the other side, the purpose of this paper is to help managers understand how to deal with the problem of order allocation in the two‐echelon logistics service supply chain better in the case of emergency.
Design/methodology/approach
The paper presents a multi‐objective planning model for emergency order allocation and then uses numerical methods with LINGO 8.0 software to identify the model's properties. The application of the order allocation model is then presented by means of a case study.
Findings
With the augment of uncertainty, the general cost of logistics service integrator (LSI) is increasing, while the total satisfaction of all functional logistics service providers (FLSPs) is decreasing, as well as the capacity reliability; at the same time the emergency cost coefficient is closely correlative with the satisfaction and general penalty intensity of FLSPs; finally, the larger the emergency cost coefficient is, the more satisfaction of FLSPs, but the capacity reliability goes up first and down later.
Research limitations/implications
Management should note that it is not better when emergency cost coefficient is bigger. The general satisfaction degree of FLSP increases with the augment of emergency cost coefficient, but there is an upper limit of the value, i.e. it will not increase indefinitely with the augment of emergency cost coefficient. This paper also has some limitations. The optional emergency cost coefficient only adopted a group of data to analyze while the trend of the reliability of logistics capacity needs to be further discussed. In addition, the algorithm of emergency order allocation model in the case of multi‐objective remains to be solved.
Practical implications
Under emergency conditions, LSIs can adopt this kind of model to manage their FLSPs to obtain the higher logistics performance. But LSIs should be careful selecting emergency cost coefficient. In accordance with different degrees of emergency logistics demand, LSIs can determine reasonable emergency cost coefficient, but not the bigger, the better, on the premise that LSIs acquire maximum capacity guarantee degree and overall satisfaction degree of FLSPs. FLSPs can make contract bargaining of reasonable emergency coefficient with LSIs to make both sides get the best returns and realize the benefit balance.
Originality/value
Many studies have emphasized the capacity allocation of manufactures, order allocation of manufacturing supply chain and scheduling model of emergency resources without monographic study of supply chain order allocation of logistics service. Because the satisfaction degree of FLSPs the cost of integrators needs to be considered in the process of order allocation, and the inventory cost of capacity does not exist, it is different from the issue of capacity allocation planning of manufacture supply chain. Meanwhile, the match of different kinds of logistics service capacity must be considered for the reason of the integrated feature of logistics service. Additionally, cost is not the most important decision objective because of the characteristics of demand uncertainty and weak economy. Accordingly, this paper considers these issues.
