Knowledge-oriented modeling for influencing factors of battle damage in military industrial logistics: An integrated method

Modeling influencing factors of battle damage is one of essential works in implementing military industrial logistics simulation to explore battle damage laws knowledge. However, one of key challenges in designing the simulation system could be how to reasonably determine simulation model input and build a bridge to link battle damage model and battle damage laws knowledge. In this paper, we propose a novel knowledge-oriented modeling method for influencing factors of battle damage in military industrial logistics, integrating conceptual analysis, conceptual modeling, quantitative modeling and simulation implementation. We conceptualize influencing factors of battle damage by using the principle of hierarchical decomposition, thus classifying the related battle damage knowledge logically. Then, we construct the conceptual model of influencing factors of battle damage by using Entity-Relationship approach, thus describing their interactions reasonably. Subsequently, we extract the important influencing factors by using social network analysis, thus evaluating their importance quantitatively and further clarifying the elements of simulation. Finally, we develop an agent-based military industry logistics simulation system by taking the modeling results on influencing factors of battle damage as simulation model input, and obtain simulation model output, i.e., new battle damage laws knowledge, thus verifying feasibility and effectiveness of the proposed method. The results show that this method can be used to support human decision-making and action.     

Self-Defense Militias,Death Squads,and State Outsourcing of Violence in India and Turkey

What explains the variation in states’ nonstate partners in civil warfare? States often use nonstate actors to do what their regular military forces cannot do well – navigate the local population. Some of their nonstate partners are ordinary civilians, while others are battle-hardened fighters with a rebellious or criminal past. The choice of proxy carries serious implications for the patterns and effects of violence during civil war, human rights, and international security. This article is the first to disaggregate the nonstate counterinsurgents and offer an explanation for why and how states use each type. It brings together the politics of collaboration with the politics of exploitation. The article shows that the state’s use of nonstate proxies is shaped by the supply of willing collaborators, the state’s ability to exercise control over them, and the trade-offs underlying the use of the different types of nonstate actors. The empirical evidence used to support this argument comes from a novel, comparative study of Turkey’s counterinsurgency campaign against Kurdish separatists and India’s counterinsurgency against Kashmiri separatists. The original data were collected through fieldwork in the disputed territories of each country.     

Allies at arm’s length: Redefining Egyptian–Soviet relations in the 1967 Arab–Israeli war

This article examines Egyptian–Soviet relations in the run up to the 1967 Arab–Israeli war. It argues that Egypt and the Soviet Union stumbled into brinkmanship with little coordination and no agreement on common objectives or goals. The article demonstrates how frustration and mutual disappointment were recurring features of the interactions between the two allies during the critical weeks prior to the war. In doing so, the article exposes new aspects of how Cairo and Moscow managed their alliance and assesses what that means to our understanding of the origins of this transformative war. These conclusions challenge revisionist accounts that attribute the start of the war to Egyptian–Soviet collusion and some traditional narratives that present the Soviet Union as an enterprising risk-taker invested in regional brinkmanship. The article draws heavily on Egyptian and Arabic language sources to examine Egyptian–Soviet interactions during this key period of Middle Eastern history.     

Factional politics in the Iran–Iraq war

This article examines the domestic causes of the Iran–Iraq War. It delves into secret discussions among Iranian political and military elites during the conflict, their analyses of their own performance on the battlefield, and their revealing public disputes and blame game decades later. It contends that an underexplored and yet critical driving force behind Iran’s prosecution of the war was factional politics. Along with state-level geo-strategic, regime-level security and individual-level ideological concerns, factional factors must also be examined to understand Tehran's war-time decisions. Iran’s factional rivalries began between the Islamists and the nationalists; and between the Islamic Revolutionary Guard Corps (IRGC) and the army at war’s outbreak, and eventually penetrated into the heart of the Islamist camp between the militant clerics and the IRGC.
