In this well-presented but not thoroughly well-reasoned argument, the vice president claims that the company profits should increase by resuming delude alpaca overcoats. To justify his dissertation, he cites a comparison between the market situation five years ago and now. The argument appears to be somewhat convincing at first glance. But further consideration reveals that this argument is fraught with dubious assumptions, which render it unconvincing from logical perspectives.
First, he only tells us that the company has a new fabric supplier without further information about this supplier. He assumes that the new one should be a good one. However, this is not necessarily the case. We even can't assure that such supplier is better than the one five years ago, let alone it can meet the company's demand for the delude alpaca overcoats. In addition, the author assumes that the discontinuing of the production just comes from the reliability of the suppliers. He overlooks a myriad of other possible reasons for it. Perhaps, the lagging technology or the mismanagement led to that result
Even if the intrinsic factors such as fabric supplier and the management have turned good enough, the vice president's optimistic attitude toward the market is still unwarranted. Just as he cites, the major competition no longer makes an alpaca overcoat for five years. Such phenomenon does not represent for the great need in the local market. Instead, it might just show the poor demand of that coat.
Besides, the study of most of types of clothing prices would lend to the support to his claim on if the deluxe alpaca overcoats typify clothing of most of types. Nevertheless, the vice president provides no credible evidence that this is the case. Even if assuming that the price of the overcoat does increase, it may result from the inflation during the five years before. If so, such growth in price means nothing to the company. Even assuming that there is no inflation, the present price is not a verifiable indication of further trends because of alteration in background, along with unexpected fluctuations within the people's demand of it.
Even if the price in the future will be still in a high level, the conclusion that the profit should increase is still baseless. The profitability is a function of both revenue and expense. Thus it's entirely possible that the cost of resuming that overcoat might render it unprofitable despite its popularity and higher price. Without weighing revenue against expenses the argument's conclusion is premature at best
Overall, although the argument seems logical at first, it has several flaws as discussed above. To strengthen the argument, the author must show the existence of the great need of that coats. Besides, we should also need more information about the new fabric supplier. To better assess the vice president's recommendation, he must provide clear evidence that the growth of revenue is much more than the cost.

Words like these are redundant- you have already said the argument is well-presented but well-reasoned.
Eliminate these kinds of words and add more concrete contents- you only have around 2 sentences really meaningful in each paragraph.
New Oriental jargons are prevalent. If you continue using them, you will be ruining urself.
