小议我国航运企业内部管理控制制度的问题与解决

航运作为一种历史悠久的物资运输方式,其存在着经营成本高,风险较大,规模较大的特点。在二十一世纪的今天,我国的企业改革深度不断的加深,企业内部管理控制制度正在朝着规范化、国际化、个性化、高效化的方向发展着。但是由于在企业改革的过程当中,企业领导者对于航运企业的特殊性了解不够透彻,导致了在航运内部管理控制制度上存在着一定的问题。本文就对于在航运企业内部管理控制制度的问题上做出分析,提出解决问题的方向和建议。     

TLS系列组合式选粉机的开发

1前言在物料粉磨系统中，节能增产一直是人们努力探索解决的问题，而解决的办法始终是围绕着如何提高粉磨和分离效率这两方面来进行，为此开发了多种新型的粉磨工艺流程和设备。为提高分离效率和简化工艺流程，避免出现过粉磨而造成能源的浪费，天津院开发出了新型高效分离设备－TLS系列组合式高效选粉机。下面就该选粉机作简要介绍。2工作原理自1885年英国人Mumford和Moody发明选粉机以来，至今已经历了几次重大的变革，虽然最初的离心式选粉机仍在大量使用，也有人对其局部进行了改进，但还是无法消除其存在的三个根本性缺点：门）循环…     

小麦加工电热润麦升温系统的研制技术

根据小麦制粉工艺技术要求,小麦入磨前需要有一定量温度的水,过去无论冬夏全使用锅炉进行升温润麦。从生产实践发现,夏季起动锅炉吨粉成本太高,因此,我们研制一种电热润麦升温系统,以节约能源降低成本。 该系统总容量为1.1吨,其中容水为1.0吨,进水方式从30吨水箱中进入,给水方式是压力式。该系统出水管设在中间,根据液体内部压强公式:P=h.r;如选择最底部出水压强过大,水流量不易控制。装满水后,起动按钮两小时水温可达70℃(非供热期),即可满足生产要求使用,根据出水流量的大小调节进水流量保证系统内的设计水位平衡;再根据温度表的读数控制电热片的数量可增可减。     

煤矿安全管理能力构成要素SEM建模研究

针对煤矿安全管理能力构成要素主观性强,难以精确度量的现实问题,利用煤矿安全管理能力构成要素与影响因素间的互动关系构建SEM模型进行研究。把山东煤矿事故案例做为研究样本,利用频次分析法统计事故原因做为观测变量,以"制度要素"做为内源潜变量,"人员要素"、"设备要素"、"环境要素"做为外源潜变量,提出研究假设并构建SEM模型。     

煤矿安全管理能力影响因素结构方程建模

以煤矿矿工的调查问卷为基础数据,运用结构方程建立煤矿安全管理能力影响因素模型.从调查问卷中提取“职工、班组、企业、环境”4层次20项影响因素建立模型,以职工层次因素作为模型的内源潜变量,以其它层次因素作为模型的外源潜变量.依据模型给出的修改建议,参照相关标准,从因子负荷λ_y和λ_x、参数β、路径系数γ、外源潜变量协方差PSI矩阵、内源潜变量协方差PHI矩阵6个方面修正模型.结果表明,“班组安全建设”和“领导班子重视”需要重点关注;“安全管理部门设置”和“法律法规与政策”有待改善;“工作责任心”和“心理素质”较敏感.     

Simulation About the Growth of Chinese Firm's Safety Management Capability

Aiming at the deficiency of exterminating measures of Chinese firm safety management, a simulation model of Chinese firm's safety management capability based on the organizational learning theory, in which the simulation method of system dynamics is utilized. The level variable and rate variable are designed based on the practical situation and change situation of corresponding variables of firm's safety management capability. Simulation firms are built with accident case groups of the oil industry, chemical industry, machine industry, coal mining industry, and weapon industry. Through analyzing the simulation result, the growth law of Chinese firm's safety management capability is obtained as follows: the accumulating and the coupling of safety knowledge should be emphasized at the same time; the balance of learning behavior of individual, group and organization should be considered together; different types of Chinese firm should take different safety policies according to their practical situations.     

Simulation modeling on the growth of firm＇s safety management capability

Aiming to the deficiency of safety management measure, established simulation model about firm’s safety management capability(FSMC) based on organizational learning theory. The system dynamics(SD) method was used, in which level and rate system, variable equation and system structure flow diagram was concluded. Simulation model was verified from two aspects: first, model’s sensitivity to variable was tested from the gross of safety investment and the proportion of safety investment; second, variables dependency was checked up from the correlative variable of FSMC and organizational learning. The feasibility of simulation model is verified though these processes. Supported by the State Social Science Fund of China(07BJY080)
