Best Policy to run open queries on LIVE Database

Question

Hi Experts,
There are users who has RO access on Live database , they run open queries on Live database. Sometimes we have faced some issues on Live Database due to open queries and we can not restrict them to run as well. So would like to get your suggestion

What issue do you have? One option is tuning the query, means create proper indexes to speed up the query..
But  the user may run heavy query even being unaware  that system consumes resources, for example
--A typical parallel query...
SELECT 
    p.ProductId, 
    p.ProductNumber,
    p.ReorderPoint,
    th.TransactionId,
    RANK() OVER 
        PARTITION BY
            p.ProductId
        ORDER BY
            th.ActualCost DESC
    ) AS LineTotalRank,
    RANK() OVER
        PARTITION BY
            p.ProductId
        ORDER BY 
            th.Quantity DESC
    ) AS OrderQtyRank
FROM bigProduct AS p
INNER JOIN bigTransactionHistory AS th ON
    th.ProductId = p.ProductId
WHERE
p.ProductId BETWEEN 1001 AND 5001
GO
