    A Performance Evaluation of a Lean Reparable Pipeline in Various Demand Environments

    Get PDF
    Lean production and logistics processes were developed in the commercial sector to reduce total system costs of production while simultaneously providing high levels of customer service, increased productivity, and increased worker utilization, In 1993, the Air Force instituted the Lean Logistics program, which successfully implemented some commercial lean principles, enabling a reduction in the total reparable asset material requirement for the Air Force reparable asset pipeline. The Air Force is attempting to further implement lean production principles into depot repair in hopes of further enhancing reparable asset pipeline cost and customer service performance. However, the failure of reparable assets, which determines demand for Air Force depots can be extremely erratic and difficult to predict. A primary criticism of lean systems is their vulnerability in volatile demand environments. Therefore, the implementation of a full-scale lean approach to depot repair may not be conducive to operational success, The purpose of this research is evaluate whether the Air Force reparable pipeline operating under lean production and logistics principles can effectively support operational requirements in various demand environments. In an attempt to answer the research objective, multiple Arena simulation models of a lean reparable asset pipeline operating under various conditions were developed. A full factorial experimental design was employed and multivariate analysis of variance (MANOVA) was utilized to assess the effects of differing levels of demand variability, base and depot supply levels, and the use of premium transportation on cost and stockage effectiveness response variables

    Case Study: Effects of COVID-19 on a Mid-Size San Francisco Commercial General Construction Company

    The Covid-19 pandemic has had an adverse effect on the commercial construction industry. New safety procedures and regulations set by local government and health officials have made it difficult for construction to proceed at the efficiency level it had prior to the pandemic. The San Francisco Bay Area was subject to strict protocols starting in March of 2020 that vastly limited the capability of construction companies to perform work. This case study looks into the ways in which a mid sized commercial general construction contractor from the San Francisco Bay Area was impacted by Covid-19 and the methods they used to handle the associated challenges. While initially being closed completely from a statewide shelter in place order, the company eventually was permitted to return to work, and was tasked with developing ways to mitigate the transmission of the virus on their job sites to keep employees safe and projects open. Additionally, the company had to make adjustments from a business standpoint to keep itself profitable in the present and the future. The company’s position in a region heavily impacted by the Covid-19 Pandemic makes them a good candidate for conducting a study in this area

    Averaging Fluctuating Income of the Individual for Income Tax Purposes

    It is a familiar feature of our system of taxation that tax rates be graduated in proportion with the ability of the taxpayer to pay. As income rises, the percentage of tax is increased by the so-called surtax. For the taxpayer with approximately the same income, year after year, an annual imposition of tax according to these rates is equable; but unlucky is the individual who has high income one year and low income the next, for he must pay a substantial amount of tax over and above that which he would have had to pay had his income been level throughout the years, due to the surtaxes in the years of high income. The present Internal Revenue Code contains several provisions which in some measure alleviate this heavier burden on the individual with the fluctuating income. Substantially, however, the present law has been wrought upon the theory that it is the essence of any system of taxation that it should produce revenue ascertainable, and payable to the government, at regular intervals. Thus, at the end of each calendar or fiscal year, the taxpayer must pay a tax based on only the profits and losses of that year, necessitating the use of the yearly accounting system, unless he comes within one of the special provisions. The back-pay section, the provisions allowing a carry-back and carry-over of losses incurred in a trade or business, and the installment sales provisions may be cited as examples of the present day allowance of proration of income over several years\u27 time; but these apply only in specific situations and are hedged around with so many conditions that few can take advantage of them. These scattered provisions have apparently been the result of a rather obviously unequal tax burden in certain situtions, and consequently have been limited in scope; and they have also been the subject, in most cases, of a narrow construction by the courts and by the commissioner. It is proposed herein to examine what can and, if possible, what should be done to ease the burden still applicable to the greater number of taxpayers with fluctuating incomes
